I could have posted this in one of the hobby pet peeves thread but because it comes up many times every year on here I thought it would be better to start a thread about it.
If you're comparing a cards scarcity to the T206 Wagner the particular cards scarcity like the Wagner should be based on that particular cards scarcity in the set that it's in for the true scarcity of that card.
Here are the numbers on a few that are often mentioned as scarcer than the Wagner plus a couple of recently mentioned comparisons. I only used the totals of the PSA and SGC pop reports because although it's not 100% accurate it's the most accurate way to get some kind of comparison.
