1974 Royals Rookie Postcard of George Brett
 

I really wanted this card, and I guess a lot of other people did too. I was planning to bid a lot. But $1750.00? What are everyone's thoughts about this price? https://www.ebay.com/itm/296575265272

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.

I agree with you completely that I'd much rather have the 1974 postcard than the 1975 Topps. I was just surprised to see that price for a card from that era that's not graded PSA9 or 10. I thought I might have an opportunity to buy it because it was ungraded and there's no reason to believe it would grade higher than a 5. I obviously was wrong. I mostly buy pre-war, so I guess I just misjudged the value of this card, and thought that the higher prices were reserved only for perfectly mint cards in the 1970s era.

I offered one here a year or so ago and got almost no interest.
