I found this coin in a lot of uncleaned ancients. It was completely covered both sides with some thick hard white material. I have taken a long time to prep it. It appears to be silver all the way through. No pattern at all. Then what looks like the number 2 shows up. Any ideas would be very helpful.
Probably an Austro-Hungarian 2 Filler ca. 1916-1918, not silver but iron, check it out here: https://numizmarket.hu/en/main-page/hungary/austro-hungarian-korona-1892-1925/details/145/11237
see the work over the "2"? I'm thinking or: https://www.allnumis.com/coins-catalog/hungary/kingdom-1920-1944/2-filler-1927-14203 but it does look to be iron, so probably a wartime issue
It´s a 2 filler coin from Hungary, probably made of iron or zinc. It´s not ancient, these were coined from the ending of XIX century up to mid-XX century if I recall correctly.
I think I can see a B under FILLER, which would make it Budapest rather than Kremnitz as a mint so likely a later emission than WW1.
