Topps 05-06 Question

[Funkadelic]

So I've come into posession of some Topps 05-06 cards, some are regular and some have the '1st edition' silver stamp on them.
My question is, does this 1st Ed. stamp degrade the value of the card :?:

i believe 1st edition topps are worth slightly more than the regular version

 

[kidd05]

They have around .10-.20 more value.

 

[Prototype]

surely key RCs would fetch a nice premium

Bogut RC 1st Ed $10
Bogut RC Norm $5

1st Ed is better (It had a shorter print)

Thats cool. I have the Bogut RC as a matter of fact.
Thanks guys.
