To help out German coin collectors, I've put together a data base of all 17th (1600's) and 18th (1700's) century mints, mint marks and the mint master and die engravers for each German State. I'm working on a very large data base for each 17th century LANDGRAVIATE, PROVINCIAL, MARGRAVIATE, GRAND DUCHY, COUNTSHIP, COUNTY, CITY, Free Cities and Bishoprics. This will take quite some time to finish. I have completed the mint's, mint mark's, mint masters and die engravers for Brunswick-Wolfenbuttel and will have more done by this weekend for the 18th century (1700's).
