How do I know if my coins are mint proof?
As a collector of cryptocurrencies, I'm often curious about the authenticity and rarity of the coins I acquire. Could you elaborate on how one can determine if their coins are considered 'mint proof'? I'm particularly interested in understanding the distinguishing characteristics that set these coins apart from regular issue coins. Are there any specific markings or serial numbers I should look for? Also, would it be advisable to seek the opinion of a professional cryptocurrency authenticator to ensure authenticity? Any advice you could offer would be greatly appreciated.
