Here's an interesting DDO for ya all - While DDO's from the CC mint aren't all that rare (and are believed to be made purposely in many cases) they are pretty cool to look at.
Well, I suppose then you wouldn't want to hear that I found this coin in a bag of circ dimes that I purchased as general melt silver, huh? You just never know sometimes...
@Treashunt there are 3 unattributed raw examples of this one on eBay right now. All three are the FS-102 which has the same reverse as the above coin.
Yeah, it's pretty clear someone in the Carson City mint was making these coins on purpose. Nevertheless, they are very cool and would make a nice (and not too expensive) challenge to obtain all the die varieties.
The dies were actually made in Philadelphia and then shipped to Carson City. Once at Carson City a Mint employee would add the CC mint mark to the reverse dies. Philadelphia created all dies and shipped them out to the branch mints.
That was a very interesting read. The article however is in regards to striking errors, which are errors occurring to a single coin or coins depending on the particular error type. These can be manufactured at any mint by the help of a mint employee. The doubled die you show us is the result of the manufacturing of a die to be used to strike multiple coins. The doubling exists on the die and transfers that impression to subsequent coins, resulting not in an error, but a variety. Dies that create these varieties all originated in Philadelphia back then. I do find it interesting that is was mated with 3 different reverse dies however.
