Re: Weak hits Errors Lead and copper and aluminum JFK's
In your first post -
Pic #1 - Hard to tell what caused the distortion here but it could be a "struck through" coin, in other words some foreign object (cloth, metal, etc.) got between the die and the coin blank.
Pic #2 - Post-mint damage. Looks like someone used it for a hockey puck!
Pic #3 - Both coins were struck on misaligned dies. If these were true off-centers the reverse side would show the same effect. Pretty common.
Second post -
- The coins with missing digits or letters are from grease-filled dies, again fairly common.
- As far as the supposed off-metal half, what does it weigh? It might be simply a counterfeit.
- I once found a half painted like a New York state quarter, 2001 I think.
