Continuity mistake: Jack and Will duel on the cart and in a side shot, the FIRST time Will crosses his two swords in front of him below his waist, the blade in his left hand is on top of the blade in his right hand, then in the following front shot, the blade in his right hand is now on top of the blade in his left hand. (00:25:15)
Continuity mistake: As Jack and Will are duelling while standing on the cart, and then up on the beams, in wide shots, Will's hair is pulled back perfectly in the ponytail, but in the close-up shots he has loose hair on the sides that is not held in the ponytail. This type of thing occurs numerous times in the film. (00:25:20)
Revealing mistake: Using the loop on Jack's shackle, Will traps Jack to the beam above with his sword. The distinctive patterns on the planks of the cart that Jack stands on differs from the patterns on the planks shown under Jack, while he hangs from the beam. It's not the same cart. Also, while Jack hangs over the cart, the cut out at the corner of the cart is seen over Jack's left shoulder. In the cut out, the linkage which is used for the wire is seen in a couple of shots. (The wire can be seen on Disc 2.) (00:25:30)
Continuity mistake: When Jack and Will are dueling in the blacksmith shop on the cart, Jack falls onto the ground. Then we get a close up of him shaking his face, watch the bone in his hair, it's bent. Then he stands up again and the bone is straight. (00:25:40)
Continuity mistake: Just before Will sends Jack up to the rafters, A close up of Jack's face shows a single hair going across his right eye. And then it's gone as he's sent up from close up. (00:25:50)
Continuity mistake: When Jack hangs onto the beam and then in some close-ups while up on the beams, as he and Will are fighting, the large bandana around his head is soaked at his forehead. However, when he holds the gun on Will, the bandana is completely dry. (00:25:55)
Continuity mistake: Just after Jack and Will have duelled, Jack gets knocked out by the drunken Mr Brown. Norrington looks at Mr Brown and says his line, yet when the camera cuts to a different view, he is now looking at Jack and not at Mr Brown. (00:25:55)
Continuity mistake: Jack and Will jump down from the beams and Jack reaches for the bag of soot (really cocoa powder). In the back shot of Will as he approaches Jack, Will has his sword in his right hand. In the front close-up of Will as Jack starts to spray him, his right hand is NOT holding the sword - we SEE his hand when he turns. In the next wide shot, Jack is still spraying the soot, Will is again holding the sword in his right hand, then Jack kicks the sword out of Will's hand. (00:26:15)
Continuity mistake: When Jack sprays Will with the soot from the sack and kicks away Will's sword, he drops down the sack of soot onto his hat sitting on the fireplace. In the next shot, from behind Will's back, the sack of soot is not on Jack's hat, but way behind it. (00:26:20)
Continuity mistake: Either the first shot has a gratuitous view of the fort or the composite people neglected to add the fort in the second shot. Norrington says, "...this is the day that Capt. Jack Sparrow almost escaped. Take him away." The night shot that follows, shows the bridge archway, and beyond it the pier, Interceptor, the fort and its parapet. After Will breaks Jack out of prison, they approach the same archway and beyond it is the pier and Interceptor, but in this shot we don't see the fort and its parapet, nor the line that Jack slid down the day before. The camera angle is exactly the same. (00:27:15 - 00:44:30)
Visible crew/equipment: During the cannon attack on the harbour near the beginning of the film, a spring board, used to propel one of the stuntmen dressed as a sailor into the air, is visible during an explosion near the dock. (00:30:20)
Visible crew/equipment: When the Black Pearl fires on Port Royal, during the cannon fire in the town, one of the stuntmen shouts as he is being propelled into the air by a spring board and then lands on a vegetable cart. The spring board is perfectly visible behind a wheelbarrow and sack. This occurs just before the first shot of the chimney exploding. (This is another stuntman and spring board than the other mistake.) (00:30:20)
Revealing mistake: Ragetti has a wooden eye, yet, when he rubs it, it makes a funny squeeking sound. When he first comes ashore he has a wooden ball that he obviously palms instead of inserting. Mackenzie Crook, as Ragetti, wears a contact to simulate the wooden eye, and spins it around with his eye. When Pintel takes the fork with the eye out of Ragetti's socket, this ball at the end of the prongs is not made of wood. Props supplied a small rubber ball, and the air hole next to the fork prongs, with the painted 'iris' right above the prongs, can be seen. (00:30:45 - 01:25:30)
Revealing mistake: When the pirates arrive on shore at Port Royal, Ragetti and Pintel are standing in front of the boats. Ragetti has his false wood eye in his hand, as he sharpens the 'iris' with his knife point. As he does so, the eye socket does not look empty in this shot, only covered. (00:30:45)
Other mistake: Ragetti's wooden eye always moves in sync with his real one. At that time, a prosthetic eye (wooden or otherwise) would remain stationary or move around independently from the real one. Even if this is a magical benefit of his 'cursed' state, it still moves in sync when he's transformed back into mortal form. (00:30:45)
Revealing mistake: Three shots after Ragetti inserts his wooden eye at the Port Royal shore, two pirates, one with long hair wearing a cap and one bald, each holding a torch in their right hands, are running and screaming. In the background, the pirate who is sliced in the belly by Will in the later shot, is seen running forward towards Will, who's partially seen on the left in the background, but Will has NOT even left the blacksmith shop yet and the woman running in the background has had her dress' color altered so as not to resemble herself in the later shot. We see the two screaming pirates later in the foreground of the same shot, before Will crosses the sword and axe overhead. (00:30:55)
Continuity mistake: During the pirate attack on Port Royal, Will opens the door of the blacksmith shop, just as Jacoby runs past chasing a woman, and to Will's right, three men run up the stairs into the alcove as Will takes out his axe to start after Jacoby. In the very next wide shot of Will and the alcove, those three men aren't seen at all, but as soon as Will lifts the axe over his head to throw, one of those men from the previous shot is seen running up some stairs, past a shop. (00:31:10)
Continuity mistake: When Port Royal is being attacked by the pirates, Will throws an axe into Jacoby's back. The axe handle lies flat against Jacoby's back. In the next shot, when Jacoby is lying on his stomach, the axe's handle is sticking up, perpendicular to his back, making it easy for Will to run by and grab the axe quickly. (00:31:15)
Revealing mistake: During the attack on Port Royal, Will crosses his axe (left hand) and sword (right hand) overhead to block a pirate's blow and then proceeds to slice that pirate across his abdomen. Yet in the previous shot, in which another pirate with a cap stabs a man who is leaning against a stone wall, we see Will in the background on the left of the screen, having stabbed that pirate in the abdomen already. Obviously cut and the takes were edited out of sequence. (00:31:20)
Deliberate mistake: During the pirates' attack on Port Royal, when they go about cutting and slicing, it is very obvious many times, especially in close-ups, that fists, weapons, etc., do not make contact, and the victims usually have a delayed reaction or react before actually being hit. This type of thing occurs numerous times aboard Interceptor, on Tortuga, and Isla de Muerta. (00:31:20)
Answer: The curse needs the blood of everybody who took a coin from the chest. All the other pirates have already contributed so, as the movie opens, the only blood needed is Will's, substituting for his father. During the finale of the movie, Jack takes a coin from the chest, adding himself to the curse, so his blood is now required as well as Will's.

But I didn't see any blood on the coins, and none of the pirates cut themselves, even before Will became part of the mix.
Yes, the other pirates did cut themselves before Will came into it, off-screen. The lack of blood on the coins can simply be explained as most of it dripping to the bottom of the chest, it being washed away by storms blown into the cave, or by the fact that they didn't drop that much blood on it in the first place.
When they had Elizabeth they believed she was Bill Turner's daughter, but they all thought the curse had failed, none of them had cut themselves so it makes zero sense.
They had been collecting back the coins for years. During that time they repaid their own blood. All they needed was the last coin and the blood of Bill Turner to break the spell.
