Most out of production tobaccos sell at a premium. There is no more supply to meet demand. Certain star names cost considerably more because they're star names. I've willingly paid more for a vintage tin of something that I want. But I don't pretend that I'm getting a bargain or anyone is doing me a favor. That's not what the secondary tobacco market is about. It's about cashing in on rare or out of production weed by making it available for purchase. Like any market, price is set by the buyers. If the price is worth it to you to satisfy your curiosity, buy the weed.
I loved McClelland Reds like Christmas Cheer, McCranies, and the 40th, and I stocked up on those, as well as the Numbers, several bulks, and some of their very highly regarded premium Virginias, because I knew that the day would come when McClelland would close its doors. That was inevitable.
I tried the Frogs and didn't like them. Aside from the Grand Orientals, I didn't much care for McClelland's English or Oriental blends. I don't think these were McClelland's best output.
What I would suggest is that you try out blends that are in production from other companies, blends that you can stock up on and let age without denuding your bank account, and before these other blends are forced off the market in a few years by the FDA Deeming laws.
But if you gotta smoke the Frog, you gotta pay for the privilege.
