I found some errors or missing data among coins from Czechoslovak Federal Republic 1991-93:
1) It could be nice to write in notice for 1 halier 1991 and 1 halier 1992 that they are only in mint sets
2) 2 koruny from British Royal Mint (Llantrisant) were mint in 1991 not in 1992.
3) 5 korun 1991 was mint in British Royal Mint and not in Leningrad mint (Leningrad in this time was already renamed to St. Petersburg)
4) 10 korun with bust of T. G. Masaryk was not mint in 1992. It was mint in 1990 (5 different variants of author including RONAI variant) and 1993 only.
1) done, thanks
2) in fact there are different informations on this one
WC says 1991 is either Kremnica or Leningrad, and 1992 is without a mark (=which could only be
the remaining Royal Mint?); Schön & Schön catalog says 1991 for Royal Mint, and 1991/1992 for Kremnica.
In opposition to WC which has 2 times the 1992 and only one 1991 mintage. So I'm not sure on this...
maybe we should just delete the comments
3) same for 5 Korun: Schön & Schön catalog says 1991 for Royal Mint, and 1991/1992 for Kremnica,
WC has it like it is on the coin's sheet here (Kremnica, Leningad/St.Petersburg and mint set)
maybe we should just delete the comments, too
4) oh big mistake for this one. thanks. transferred collections to https://en.numista.com/catalogue/pieces3976.html
Thank you for update. I am Slovak living in Canadian Montreal and it is a reason, why I am collecting coins of my country of origin. I have all these coins and I can provide pictures of differences on the rims. Standard catalog of World Coins 1901-2000 has the same information about mintage of these coins (2 and 5 korun 1991) as all Czech/Slovak sources which I am following. I think you could leave notice there. Leningrad was used by Czechoslovakia in year 1953 for some aluminium coins (maybe we can open this issue later?)
I would like to put in database some missing mintage and parameters of Czechoslovakia coins from socialims period. Are you also responsible for this?
yes, I did Czech and Czechoslovakian coins some months ago. On base of WC catalogs and Schön & Schön. Well - I don't really know what to do with this contradicitve information.
If you say so - I will add comments. According to the addtional data I posted above what would you
propose to be added?
cAN YOU PLEASE GIVE SOME DETAILS OF HOW TO DIFFERENTIATE BETWEEN THESE MINTS, I THINK I HAVE A COMPLETE SET OF 1991 COINS WITH mINTMARK "R" UNDER THE dATE, BUT YET I AM CONFUSED ON HOW TO DIFFERENTIATE THE MINTS OF 1991-1992 COINS, PLEASE DEFINE IT, THANK YOU VERY MUCH
OK, i see it, that is little helpful, bt i suppose that mintmark "R" must also mean something and there must be the other letter too for the other mint. both mints must not be using the same letter. That is not logical
Lev, probably you know where made the coins of Czech Slovak Federal Republic in 1991 from 10 Haleru to 1 Koruna? What does the letter: R (Rome) under the date?
