I'd say supply and demand. Guessing that quite a lot of Regulators were sold and most of us that had to have one or more, got them. I know I did. Some people's interests change and got to move them to refine their collection. Some day they may regret letting it go, especially as the value increases as they certainly will. You can bet some of these investments are sitting in safes to finance future wants or to make a Buck. Nothing wrong with that, I wish had a little more discretionary funds to enjoy the trading up game.
