What a cool idea. I may consider starting a collection. A quick look shows about 64 dates between 1500 and 2000. I have a lot of old European minors and probably have nearly all after 1700 and some in the 1600s
It has been a fun set to do. Additions are slowing down now that I'm complete 1723 through 1951. By all means start one up. I need some company in the "Showcases, Other" category.
