Hahaha Have you read those small black words under my name? They say Borderline Hoarder. I'm a collector not a flipper. Just saying.
I'm a collector, too. But not AGEs. So it's just another commodity for me. And if I have a guaranteed buy-low/sell-high situation for any commodity, I'm on it.
And when they do it that way, all you hear are complaints about how the mint sold an overpriced item that collapsed and had no aftermarket except at below issue prices. Like you said everyone who wants one, got one, and now there is no aftermarket. People are unrealistic. They expect the mint to make popular, low mintage, high demand items that will increase in value, and make it easy for THEM to get them so they can flip them for a good profit.
And you will have collectors like me who avoid the mint almost completely. I might buy one Proof set a year from the mint if I can't get from my local dealer because of Covid. The mint's purpose is not to make profits for its customers. It's purpose to supply coins to people who want them. I don't give a damn about these dealers who profit from the mint's games. I have never bought a thing from most of those dealers. If they have to depend on the mint's sweetheart deals to stay in business, then they need to find another line of work.
The kind of coins that I buy are less than $50. However, if I am missing a coin that fits in a set, I will go up to $75.
