Hi, I'm not a coin collector just here looking for a little help! My son bought a box of books at a yard sale & inside was a small box of coins. Coins were all foreign (I'm in the USA) & dated from the mid 1900's thru the 1980's. Except for these 2 are dated in the 1700's. I have a hard time believing that they are real. Can anyone tell me for sure? And if course I would like to know if they are worth anything. Any help would be greatly appreciated. Thanks! Pics attached
That verdigris is an indicator of them being real, however you should look into stopping it, I had a coin with some verdigris on it, after many years it made a whole in the coin. Don't clean before knowing what you're doing or you may destroy them. @BadThad
You might want to ask a moderator if they can move your post to ancient coins forum, you'd probably get more help. Hope they're real!
I'm having trouble believing that they're real though. The fields, especially on the Britannia side look like a fake coin to me. With that said, back in the 1700's coins were crudely made so they may be real. Yes, better pics may help.
Look authentic to me. Weight would determine the denomination since the Brits didn't put denominations on their coins back then.
