Hi, this is my first post so any help is welcome. After 50 years I am back into stamps, I have bought a huge lot from auction, this is the first question of many I expect.
I have 2 stamps from Hungary that are overprinted as shown, they also have full gum to the back and have not been hinged. From internet searches I have done, there have been fakes made of these stamps, how do I tell if they are good or fake.
Thank you for any information.
