I have some 2 florint coins (1970), 1 florint coin, a 10 filler (1977), and a Hong Kong dollar (1970). I also have a 10 kopeck coin from 1951. Are any of these even remotely rare?
Welcome to the forum Yuber. Assuming that "florint" is a typographical error for "forint", a Hungarian denomination, your 1970 2 forint is brass, from a mintage of 45,195,000, valued in the Standard Catalog of World Coins 2005 32nd Ed. at up to $4 uncirculated, as KM#591. There are three varieties of 1 forint coins, all aluminum, minted between 1948 and 1999, with mintages from 30,000 to 60,000,000. Their values range up to $16 uncirculated. Also aluminum, Hungarian KM#572, mintage 30,075,000, value up to $2.50 uncirculated. KM#31.1, copper-nickle, 15,000,000 minted at the Heaton Mint in England, maximum value $5.50. U.S.S.R., Y#112, aluminum-bronze, mintage unknown, maximum value $8. Without clear pictures there is no way to estimate the grade/condition of any of your coins, so bear in mind that in heavily circulated condition none of them are worth more than a few cents.
The Forint was also struck as a silver coin under the Austro-Hungarian Empire.It was last coined in 1892 under Emperor Franz Josef (ruled 1848-1916). Aidan.
