Rule of thumb. If it's too good to be true, it usually is. The Chinese have been cranking these out for some years now. The other popular Chinese made rarity US coin is the copper 1943 penny.
My bad Tracey, I obviously saw "look what I sold" and that's not what you said. A lot of times the chinese or counterfeiter, will buy a coin then make a mold from the coin. They will then use it to make copy dies. These usually only fool the uneducated buyer. But there are many contemporary counterfeits that have even fooled the TPG's
