It is a DDO
. But a lot of these were master die issues. (Probably the reason the images are not there) But check Wexler's site to see if it is one of these master die/master hub
Denver Mint WDDO'shttp://doubleddie.com/1598998.htmlmaster die/master hub What does that mean?
The dies are created through a chain of proceedures:
Note the chain at the top:
Master hub. This is a positive hub. (that means the devices look like a coin)
Master die. This is a negative die. (that means the devices don't look like a coin mirror image opposites, incuse and raised devices are opposite the coins.) Only two of these are created. (usually)
Working hub. These are also positives like a coin, but used to create working dies.
Working die. These are also negatives and strike the positve coins we use.
[red]So what happens when these dies are not exactly correct?
1. All coins from a miss hubbed die, will all show the same doubling. (A doubled die is created)
2. Doubling on a hub. All dies created with this hub will have many dies created exactly alike the same hub doubling.
3. Doubling on the master die. If this happens on a master die, because two are made, that means that 1/2 of all the coins that year will have dies striking the exact same doubling.
4. Doubled master hub: Means that all dies will have the same doubling as all down the chain the dies will all look the same.
Of course you could have a doubled die on a doubled master die as well, that would be a variety. (IE: 1972 die #009)
Also they would have started the process of using, then discovered the issue and then would have re-created a whole new chain, or fixed the issue with an new master die and scrapped all the faulted dies/hubs/master dies/master hubs. So this years dies are savers for now until they figure out which ones are real doubled dies, (not master hub/master die issues) Wexler lists some that he has figured out.CoopHome
