They’re pretty. They don’t have denominations, so they appeal to the non-dollars crowd in addition to tournament players. I’m not sure how many runs, or how big of a run was produced. This was one of the later Paulson home molds. It also seems like people have some pretty healthy sets of these. If a jillion were made, the last point might not be significant.
edit to add: More than a couple sets of these may have gone to Europe, which is usually a one-way trip due to transit costs and taxes.
Anyway, welcome to the forum!
