john1: I have a collection of over 80 types of machine struck square coins, almost all of which came out of dealers' junk boxes. Collected over a period of about 15 years, the average current dollar price paid of around a buck each.
It was a fun collection to build over a peiod of about 15 years.
Still need Aruba 5 Florins 1995 - 2004, and Sri Lanka 10 Rupees IYSH commemorative. You name it, I have everything else, except some gold ones.
