Hi At once I am sorry for my English, I write with the help of Google translator. I ask for help from the experts, I think first of all from the UK. I came across these two coins (one penny 1921 and 1967). They are both made of white metal (such as copper - nickel). But in catalog Krause says "Composition: Bronze" (KM # 810 and KM # 897). Ie color coins should be red-brown but not white. Option fakes think possible to rule out - well, what meaning to counterfeit 1p. I know that there are a variety of coin minting errors. Met whether anyone similar coins? I met for the first time are not seen and at auctions. Many thanks in advance. Alex. PS: Necessary photo - provided later. Now for technical reasons can not.
