I have a question regarding Japanese Coin Variety attributions...

devious

Where does KM-13 come from? Is there a reference for this and what the value may be in AU grade? I ask because I can look in the world coin catalog and find it as a C#13 and PCGS does list a lot of C#XX japanese coins. What gets me is why are they not standardized varieties? Why would this become a KM-13 and not a C#13? Any advice on how this works would be greatly appreciated and just where exactly KM-13 comes from?

Thanks!

You'll probably also notice a lot of Y numbers in Krause. Those are holdovers from RS Yeoman's old standard catalogs, which were popular before Krause came on the scene. The C numbers in Krause are holdovers from Coins of the World 1750-1850 by William Craig, which covered areas not treated by Yeoman. For Japan in Krause:

C# 13 is a rectangular, silver 2 shu from the early 1800s (prices listed only up to XF).

Y# 13 is a gold 20 yen from the late 1800s (which not many people can afford, the "cheap" one is $20k in F!)

There are KM #s in the 1600s book, but they make no sense (to me at least).. starting at 5 going intermittently to 99. There are also FR #s in that book. But no 13 for either.

I don't know why, but Krause stuck with the Y numbers for more modern Japanese stuff.

I'm not entirely sure about the rest of the question or exactly which coin you're referring to.. I'm pretty clueless on slab stuff.

Thanks for the response.

That's my thing, it is a C#13 but they cataloged the variety as a KM-13 and hence me asking. PCGS has many other C#XX in the database and a few KM-X, but I suppose I was wondering why they didn't just attribute it as the C#13 and why they did the KM-13 and where KM-13 originated from?

I have seen both PCGS and NGC occasionally put the "KM" prefix on a slab for a coin that the catalog lists with a "Y" prefix, and I suppose the same thing could happen with a "C" prefix. In a perfect world, the TPG label would absolutely match the catalog entry, but . . .
