For as long as I've been collecting glass sugars & creamers, sun-purpled glass has been on the fringes. I know it's been a problem with bottles and insulators, but it just didn't intrude into sugars & creamers much. Then, about 15 years ago, really dark purple pieces like this Fostoria American set began appearing on eBay, and while I was shocked at the blatant fraud of attempting to sell these items as "Rare purple American", others happily purchased them, sometimes at 10x their worth as crystal pieces. I always wanted to ask one of these buyers if they really believed that this was a rare Fostoria color, or if they just wanted the item for the novelty. Fostoria sugars & creamers seemed to really get targeted. Something about their 1940s-60s crystal glass formula must make them more suitable to purpling than other elegant glass companies.
The Fostoria crystal Coin set was another that seemed to get artificially irradiated a lot, likely because it attracted buyers. I documented an irradiated Coin set (sugar, creamer, lid) which sold for $215. Today you can buy a crystal Coin set for less than $15. Both the crystal Coin and American sets are common today, so seeing something like this get irradiated stings less for me than seeing it done to something uncommon, scarce, or rare. But still, I wonder: if you know enough about Fostoria to recognize Coin or American sugar & creamer sets as desirable, then you likely have heard about irradiated glass, so why spend many times the value on these sets? If anyone wants to private message me about this, I would love to learn more about the motivation. No judgment, I'm just curious.
