Twenty years ago a Texas man began innocently accumulating Eisenhower Dollars. He now has 175,000 of them and they're for sale in one lot on eBay.

"I started collecting when they stopped making them, but for no particular reason. It was just something to do. I'd find them in convenience stores, ask for them in change or buy them at face value when I ran across them. But you don't find them in circulation now," Michael Brown says.

He has a web site where you can see a picture of the mountain of coins, giving you an idea of the vast quantity. They remind me of Scrooge McDuck in his pool of gold coins.

By the way, the man shown in the picture isn't Michael Brown, it's just a security guard watching over the coins.
