Value wise, there have been 2 card backs sold recently on ebay. One was relisted as the seller is plagued by dodgy(?) bidders on a few of his most recent auctions.

The next one in my opinion is better condition....

So a card value of $112 - $180. Yours has a partial bubble but the signature spoils the card for most collectors.
Figure wise these vary from $30-$50 and on a good day can hit $75-$80
So TFB's $200 imo is a pretty good valuation.
