My collection has two distinct focal points.
#1 US and colonial 18th and 19th Century coins in silver or gold specializing in rate dates and short lived mints such as Dahlonega and Charlotte.
#2 Gold coinage of the minor European principalities, duchies, kingdoms before the amalgamation into modern countries such as Italy, Germany, Yugoslavia.
I also have a small representation of ancient Roman and Judean coins.
The value of my collection is not something I’d disclose to anyone except my insurance carrier.
