GlobalGemology Posted March 27, 2022 Report Share Posted March 27, 2022 Good morning, I'm currently appraising a large coin and currency collection but must admit I am not well versed in Russian coins. I've attached a photo of twelve 1899 Russian 10 Rouble gold coins. However, I have a suspicion that they may be counterfeit. I'd greatly appreciate any information you may have to offer. Here are the approximate specs of each coin, which is very consistant: Diameter: 22.9mm Thickness: 2.17mm Gross Weight: 7 grams From what I've read, the diameter and thickness are supposed to be 22.5mm and 2.15mm. I'm not sure if this variance is large enough to be concerned about. However, I believe the gross weight is supposed to be 8.6 grams and these only weigh 7 grams, which does set off a red flag for me. Also, there is some green oxidation on several of the coins, which I'm assuming is due to the composition not being gold. Thanks again for your help. Sincerely, Scott Quote Link to comment Share on other sites More sharing options...

alexbq2 Posted March 28, 2022 Report Share Posted March 28, 2022 There's fake everything in Russian numismatics. To your point these could be contemporary counterfeits as well. They look gold plated to me. Quote Link to comment Share on other sites More sharing options...
