LostDutchman Posted November 17, 2005 Report Share Posted November 17, 2005 Proof Errors – Errors occuring on proof coins are highly rare as they are held to much higher standards than circulating coinage. In the 60's and 70's major proof errors (double strikes and so on) were smuggled out of the mint and offered on the market. Quote Link to comment Share on other sites More sharing options...
