Hi xledzeppzosox,
In my opinion, yes it will be a collectible. In fact since SOG last stopped producing the knives that had the '20th Anniversary logo' all the knives that had those immediately became collectible.

Even shops that had the exact model don't know if their knives have the logo unless they open up the box and check the knife I think.
You should keep the knife and it will have some value to a collector (or to yourself) a few years down the road. Just like how the "Seki Japan" knives now have become
somewhat a collectible series now that the SOG fixed blades are mostly made in Taiwan.
Just my 2 cents worth. Most people say that 'the value of a knife is what a person is willing to pay for it'. That is a rather vague and BS answer to me.
Cheers,
Mark
