This is what, like 1/3 of what a PSA 9 '75 topps goes for?

Rare true rookie issue vs 1975 topps with a gazillion made. Choice is clear in my eyes.

A bargain price for somebody who wants to have a Brett collection that stands out from the rest. These kinds of items to me will only ever go up in value, and if you get the right people possibly by large amounts at a time.

These kinds of items people also want to buy for 100 bucks but when it comes to selling they want 3 grand. In that sense they are one of the few types of issues I think actually can do better in an auction. Skip all the joke offers (and trust me that is the vast majority) and get the people who actually want something rare and will pay you what it's worth to them.
For some reason pre war really has this down right but post war it just falls apart, imagine a t206 cobb, a few thousand dollars right? Now what about his 1907 sporting Life Cabinet? A quarter million?

Sorry, small tangent.
