So, I've posted a solid hand full of coins in this section since joining this site and thus far only one has proven to be a true mint error. But I stumbled upon this dime this week and I'm pretty sure I have a winner. Seems to be missing a portion of the clad layer. What do those more knowledgeable than I think? Reverse is standard so I'm not going to bother posting that
Will it weigh slightly different if part of the clad layer is missing? I'll weigh it once I get another scale, the digital components and calibration on my current one are broken.
It depends on when the clad layer became missing. If it happened before the blank was made then no, the coin should weigh the same as a normal dime. If the clad layer came off after blanking then the coin would weigh slightly less than normal. Like Chris said, there is probably not enough material missing to accurately weigh when the layer became missing.
Are there any important factors with missing clad layer coins that increase potential value to collectors? For example, if the missing clad layer makes up a larger area of the surface would it therefore be a more collectable error coin?
Yeah, send it to ANACS for attribution. Otherwise, it is not worth much more than $.10. I would also think larger coins would sell better than the dime. More missing clad layer would add a bonus point or two.
