It's all relative. I imagine $400 grand would barely cover Teresa Heinz's monthly clothing "budget" or Michael Jackson's Neverland Ranch maintance fees.
$112K+ 1943 for a copper penny. About 40 of them known to exist. There was a CU shortage during WWII.
That's absurd.
You've never heard of eBay, have you? :-)
Babe Ruth's bat that he used to hit his first home run in Yankee Stadium went for $1.25 million last week. My favorite bat is 34 ounces, and coach says that is too much to get good bat speed, but the Babe's is 46 oz.
It has less to do with actual value or investments than with collecting. For some rich guy, $400,000 is the end of a long hunt.

I have a whole jar full you can have for $200,000!!
