That's D-O-I-L-Y, with an "i", not "Dolly". Nice! They're pretty rare. At one time, I believe just about any coin in a Doily holder would be worth $150-200-ish, minimum, just for the plastic. This thread on Collectors Universe may interest you. Back in the early 2000s, I sold an 1854 PCGS MS65 RD large cent in a Doily holder. It was a consignment- I could not afford the coin for myself. I wish I could have. It sold for $2,500 or so at the time, as I recall. A year or two later, I saw the very same coin in a dealer's case at one of the FUN shows, and it was not the person to whom I had sold the coin on eBay, so it had changed hands. Small world. The price had gone up considerably, too. I wanna say it had gone up to $4K-something. Don't remember exactly. It was a nice coin. I wonder if it is still in the Doily holder today.
There are 2 of them for sale on ebay now. Sorry for the misspelling but the sale said Dolly. Guess that person didn't know either. Never saw them before.
