A $700 Jan Murray?

In going through Los Angeles items on EBay, I try to select ones that are interesting or unusual--and reasonably priced. I usually filter out what I consider junk, but this one is worth a comment. Here's a basic bread-and-butter letter from TV comic Jan Murray that has been listed on EBay with a starting price of $500 or Buy It Now for $700. No disrespect, but I wouldn't pay $700 for a Jan Murray even if you threw in a Larry Storch, a Charley Weaver and a Wally Cox.
