Shorts are unusual in the coin business, and they're typically private deals between two dealers. For example, I might commit to deliver 1000 bags of 1964 Kennedy half dollars to a retail marketing firm at a fixed price. In which case I would hedge the bullion value by buying futures, leaving myself long silver and short JFKs. Then, I would round up the coins, deliver them at the agreed price, and close the bullion hedge. But if I have trouble finding the coins, I may get "squeezed", have to pay higher than expected premiums, and lose my shirt.
Now I'm not saying that there's a big short or a squeeze in the commem market right now. Certainly, if there were, we could join forces to buy all of the available commems and crush the dealer who was short commems. But if there's no short, there's no squeeze, because nobody out there actually needs to buy the coins.
But does that mean there's no opportunity to drive the market higher? Couldn't we all join forces and decide we're going to run the commem market to the moon? I think it could be done, it could be profitable, and it would be a lot of fun.
And BTW, of course, this is not financial advice, etc.
