First up is a graded coin I can give you the precise answer for. The 1817 more like a check too see if I'm on the right lines with it as its a little awkward due to die flaws and the fact they weren't struck well in the first place. A godless florin And Brunswick - Wolfenbuttel 24 Mariengroschen's 1817, 1820 & 1821
I can't tell you yet as I've not received it but I believe it might be on the slab. You're wrong though
I'd say AU 53 then. After looking again, I don't see obvious wear. I do see a little bit on the reverse, on the lions and more on the horse to the right.
You must have found it on the Internet ? Au53 exactly ha either that or you're really good I'm not very good with American grades especially when it comes to AU. To me it's either UNC or EF ! I would put it in gVF maybe just EF in old English terms
Wow. I was right? I honestly didn't look it up. I got lucky! I'm quite familiar with American grading, so maybe it helps even with world coins. Usually AU coins have a lot of luster but that's with a little more recent coins than yours. Your coin I could tell has original surfaces and little wear so an AU is fitting. In the Krause catalog they only list xf and unc for world coins, so maybe that's common everywhere else. We Americans may be more fanatical about grading
AU53 US grade is definitely in the ball park on the first one. I was thinking AU50. I think both of those translate roughly into an English EF.
