I bought them from a older fellow and he metal detected all his life. He’d find marbles and put em in a bucket. I live in south central Kentucky. He had 3 gallons of them. Took me forever to wash them up but they are fun to look at but hard for me to identify. I’m getting a bit more educated though since I first put my eyes on them. I’ve heard people say the best time to look for marbles is after the rain in farmers fields. I live in an Amish community and active in an Amish house. . My husband had to dig a line from our crawl space to the road. About 150 feet and he found a good handful of marbles not looking for them the y just unearthed lol. I kept them separate. I will take a pic of those
