Actual Walter Gardiner signature on COA. Add value? How much?

[Dave Thinkstoomuch]

I recently purchased a knife (see "Harry Gant" thread I started) that is 1 of 5000 limited edition. I know Schrade always supplied a COA (certificate of authenticity) with their limited editions but usually this was just an "official" printed piece of paper with no signatures. I have now discovered a number of other examples of this same knife and they all have unsigned COAs. My knife's (#0010 out of 5000) COA is signed-with-a-pen by Walt Gardiner himself. How rarely did Mr. Gardiner hand-sign COAs? How much value might this add to a particular knife seeing as how it might make a series 1 of 5000 into 1 of 100 or even 1 of 10 depending on how many he chose to sign? Was/is Walt Gardiner a big Nascar fan? Would the promo-guys have put him up to it or would he have insisted himself because he liked seeing his signature beside "Handsome Harry"'s? Any thoughts appreciated...Thanks

As I've received no responses. I'm thinking now that Gardiner signature is quite rare. Does anyone have knives with signed COAs? Any examples at all?
