text: is an fbi sign that was signed by j edgar hoover worth any real money? i'm selling items on ebay and a friend wants me to sell it for her, but i'm not even sure if she'll get much out of it. i keep looking it up, but it just tells me info on hoover, not on the sign or the price... you should give it a try anyway..i'm sure some collector will step up..it is a part of history..
