I bought a coin yesterday that isn't in Numista and want to add it. I have found the coin but on another site, but a variation exists that could be closer to mine. The other site references the 188 Page Mertens book and that mine could be Variation 30b)
I have found the book Münz- und Geldgeschichte der Stadt Northeim, etc (Münzstudien. Bd. 4.) Unknown Binding – 1 Jan. 1928
by Eberhard Mertens (Author)
in a few national libraries, but wondered if anyone has a copy and could identify 30b, or tell me where I can get a copy of the book.
From that helpful link, it looks like there could be two date lines, 1554 and 1555.
You could just list the catalog reference as Mertens 30 for the 1554, and in the Comments section write "Varieties exist" and reference the two different reverse legends.
Please ignore I just saw the book creation request was already made
