If the photo did not have so much motion, I suspect some could be IDed by some here but these do look like why we don't suggest buying by the thousand.
Welcome again to CoinTalk @Silver Rider. Only two years to clean 1000 coins less these? That was very fast. It takes me months to clean a few coins working on them at the same time. I am sure I don't have enough life left in me to clean 1000 coins. Would love to see some of your successfully cleaned ancient coins. LaC
Silver Rider, Before I opened your thread I expected to see something like this, see photos below. This is the famous Wilton Cross in the British Museum, a Byzantine gold cross set with a solidus of Heraclius & his young son, AD 613-641. The front of the cross is inset with garnets & oddly shows the coin upside down . The back side of the cross is undecorated. I wish their staff would remove those distracting numbers . I joined CoinTalk last year & have found it a rewarding experience & hope you do also.
