IMO I think it is kind of silly to consider that type of thing a 1/1.
As most know I started with sports card collecting and a few years back some of the manufacturers started doing these stupid stamping cards BS thing at shows. So say you buy a special pack from them at a show (either at their booth or sometimes they will make special boxes for the show) and they stamp the cards (for example) spring expo 1/1 or 1/5, Even though they are putting the same cards they put in regular releases.
Now some people (though very few by now) actually feel these are more valuable cards, but I wouldn't pay any more for the stamped logo, rather I think it clutters up the card. :'(
Well just my opinion, but I think it is a ploy by the Manufacturers to trying to increase the value of their cards or products.

)Just think how much money they (TOPPS) made off doing that with that set, plus most grading companies will give better grades to cards sent from manufacturers based on the amount of money they make off of those big deals.
