Is there a weight difference in packs with game used items?

Back in 2001 I ran into a guy at Wal-Mart that was using a scale to locate Albert Pujols Rookies in Topps Chrome. He said that because of the lack of clear coat on the Pujols card (because of his late addition to the set) made it weigh less and, therefore, he could just purchase the packs with the Pujols card. I was just wondering if this same concept could be applied to memorbilia cards? Would these weigh more (or less) than a regular card? Has anyone ever tried it? And, most important, how big of a dork does this make one look if you are in Wal-Mart with a scale and weighing every pack?

I would pay children a hefty sum to harass any dorky adult weighing or searching packs in a retail store.
Not a dork but a fun sucking, money hungry jerk.
I actually have bought 2 "hot packs" online to see the surprise on my boys faces when they opened them so Im guily in aiding and inbedding but this is something many frown upon. I on occasion talk down to those I see doing it. So far no black eyes.
As long as Gary isn't the one dividing everything up.

1. probably get banned from the shop or
2. You would not want to be thought of as the type of person who would do that type of thing by other collectors
So the question is... if you would not do it at the hobby store, why would it be OK at Walmart?

<< <i>Would you weigh them at your local card shop? Probably not since you would likely either:

But here is the problem...those scumbags could care less what anyone else thinks because they have tunnel vision to having an advantage for the almighty dollar.

Why step over the dollar to get to the cent? Because it's a 55DDO.

Because Walmart is evil.
But that still doesn't make it right.
