50 Old Coins of the 17th-19th Centuries Restoration and Preservation

I Tried Restoring 50 Old Coins for 10 Days. 50 Old Coins Restoration. In this video I showed the restoration and preservation of old coins. I found these coins with a metal detector. Coins of the 18th-19th and early 20th centuries. There was a lot of dirt and oxide on the coins. I decided to restore and preserve old coins. I removed the dirt and did not damage the original patina of the coins. I hope you enjoyed my restoration video.
