ScottI think there are two different situations here, and each will have different results:
1) uncatalogued issue - no cards of any pose are known.
2) uncatalogued player within a known issue.
For #1, I think cataloging the issue will increase your ability to sell the individual cards to more collectors (they'll feel more comfortable that the cards are real) and to skeptical advanced collectors. I will leave it to wealthier collectors to speculate on the affect of cataloging on price (as you already have done).
For #2, cataloging it is definitely going to drop the price in most cases, but not in all. Example: you find a t206 Tris Speaker portrait in your great-grandfather's bible. You are positive it's real and you tell your advanced collector friends about it. What would such a card bring, uncatalogued and previously unknows? So you show the card to Bob Lemke and he catalogs it a year later. You send it to Mastro. Now what will it bring?
