Agree 100% , buyers market with the exceptions you mentioned.It goes for most collectibles.The coin market is down between 20%-30%.The baseball card market has basically collapsed.
Collectibles are not a very liquid asset to have a bunch of $ in right now.
I know part of it is the economy for sure. But there are not many "New" people getting into any type of collectibles. That also affects for sure.
I mostly collect and sell coins and i can tell you that market was overpriced for a long time. Like the saying goes " all that goes up comes down" .
Everyone needs a roof over their head , not a rare coin or knife.
