OK, let me now correct my correction. I meant to say that I have the elusive 5 Fen coin dated 1979 (not a 3 Fen coin, which obviously doesn't exist). Also, just to be clear, I have all of the circulation strikes in the 1, 2 and 5 Fen denominations, which does NOT include the ones made for proof or mint sets only (with the exception of the 1979 5 Fen coin mentioned previously).
I am also trying to find out more information on the Jiao and Yuan coins issued for the years 1980, 1983 and 1984. Supposedly these were all circulation strikes (along with the proof sets), but the only thing I have managed to find for those years is the proof and/or mint sets. I have the 1, 2, & 5 Jiao and the 1 Yuan dated 1981 and the 1 & 5 Jiao and the 1 Yuan dated 1985, along with a full 1982 proof set, but I am missing all of the Jiao and Yuan coins dated 1980, 1983, 1984 and 1986 (plus the 1985 2 Jiao, which was only issued in proof sets). I know the 1986 set is in proof only and is extremely rare, but I was hoping I could find the 1980, 1983 and 1984 issues for a reasonable price.
So, if anyone knows the actual rarity and/or value of these coins, along with possible availability, please let me know.
