Several dates are in the twentieth century instead of the seventeenth century.
Based on Krause (SC German Coins, 3rd, page 22; SCWC 1601, 6th, page 260) and a web site ( https://www.aachen-muenzen.com/st%C3%A4dtische-pr%C3%A4gungen/ferdinand-ii-1619-1637/ ) these aren't error dates and the dates should be in the seventeenth century.
I can't change the dates because: “The list of years is complete and has been verified.”
Note: I have a pending modification request for the listing to fix the Krum catalog number (but that shouldn't interfere with modifications to the mintage lines).
