Rumania, being part of the former Soviet system may have some rather nasty laws for “stealing” state treasures. If he is luck he will get a percentage of the treasure or it’s value.
Actually, a wheat penny can sometimes be worth something. The important thing is the date, mint mark, and condition. You can actually look on line for coin values. Ask.Google, for coin type, in this case “Wheat Penny, current values.” There are sites which tell you how to judge the grade of the coin, which can range from Good - 8, and higher. With Good you can read the date of the coin, but there is quite a lot of wear. Values go up to Mint Proof and Uncirculated, with numbers in the 60s.
Yep. You’ve told me this, before. I should just send the pounds and pounds of pennies I have to you, LOL!
Why couldn’t he have left me a few pounds of 1800’s mint-condition Silver Dollars? ;)
