Thanks to a few readers and some additional research, I edited a few of the Numismatic Dictionary entries and added a few words. The new words added are:
The one I did not know but found the most interesting is fishscale. Fishscale was a nickname for the trime, the U.S. silver three-cent coin that was struck 1851-1873. In Canada, it was used as a nickname for their silver five-cent coin struck from 1870 through 1921. I could not find an origin of the nickname.
I am very happy that the Numismatic Dictionary has proven to be a useful resource!
As always, if you think there is a mistake or a word has been left out please contact me and let me know. Thank you!
