Since I am new to the coin community, I'm not sure if a DD is considered a "one of a kid" type of error.. ha if someone could please help with some advice I would appreciate it thanks in advance!

ijn1944 Bedrock of the Community United States 19164 Posts	Posted 05/05/2023 07:54 am Appears to be Machine Doubling, yes. It's customary to post full, large and sharp pics of the coin's obverse and reverse; then' closer-in images. The full photos provide needed context for us. Thanks. Report this Post to the Staff
Dearborn Moderator United States 96348 Posts	Posted 05/05/2023 09:02 am with MD ( Machine Doubling) on this coin. And to answer your question - No - doubled die coins will not be a 'one-of-a-kind' error. the doubling is engraved into the die and will repeat this doubling up on many coins during its life striking up coins.

-makecents- Pillar of the Community United States 8760 Posts	Posted 05/05/2023 10:35 pm Dearborn, on more than one occasion, you have used the term "engraving", in conjunction with doubled dies, I do not understand this. There is engraving of dies, most usually, masters but has nothing to do with a doubled die (hub doubling). Hub doubling is a minting error that occurs when the working hub is misaligned or mismatched with the working die. -makecents- Report this Post to the Staff
