I don't know if other collectors give this much thought, perhaps it is a concern for aging collectors more so than younger collectors. But I often wonder when will the constant back and forth buying that happens between the dealer middle men drive the prices so far up that average collectors are left by the wayside. After all each time a coin trades hands from dealer A to dealer B, then from dealer B to dealer C, and then back to the beginning from dealer C to dealer A the price has to be marked up a bit on each of those transactions.
This thought occurred to me after reading stories from other collectors who describe the actions on dealer day; and from my own experiences at coins shows both local and larger shows. I cannot recall a time at any show I have attended that I have not witnessed this almost constant back and forth between the dealers. I even setup as a local show once and saw first hand this action between the dealers.
So the question I am always left with is at what point am I going to be priced out because all the meat that was on the bone has been picked clean because all the middlemen transactions which push the prices higher and higher until the golden goose is plucked.
Maybe I'm just getting old.
