What percentage are graded?

[nat]

The poll has been running for a week, it sounds like a good time to try to draw some conclusions.

Including those mentioned in the thread, 66% of the T205 Mattys represented here are graded. There were a total of 80 cards reported.

rats60 is thinking that inactive collectors (who aren't reading net54) are less likely to have graded cards. So maybe 66% is an over-estimation. On the other hand, for sets that are less set-builder-friendly, you'd expect a higher percentage to be graded. (The hazard of doing a poll on a card from a non-set-builder-friendly set is that the sample reported wouldn't be big enough to generalize from.) So we have two considerations that are external to the poll, which would push the results in opposite directions.

So even if the over all percentage of pre-war cards that are graded is very small (and it must be), it seems that the percentage of significant pre-war cards that are graded is pretty healthy. Maybe even >50%, if the population of non-active collectors isn't too big.
