The value of gold error coins
Error coins, and particularly gold error coins, have always been favored by collectors, meaning that the price for an AU error coin can be much, much higher than for a regular coin. This is because such coins are very, very rare.
What sort of minting errors are there? Errors include:
- Partial collar (partial reeding on the coin's rim)
- Broadstruck (spread and distorted)
- Clipped planchet (a blank with a piece missing)
- Off-center strikes (self explanatory)
For an overview of these and other minting errors see Wikipedia.
