Not naming any names here. It's not one seller. It's a lot of people and a lot of crazy high prices for commons and junk, not to mention mis-id-ed marbles. I've been rolling my eyes at them for months and biting my tongue.
The example which brought me here to vent is someone asking $10 plus $5 shipping for what they're calling a near mint Vitro Conqueror. This is one where I'm not sure if the ID is correct. Could be, but I'm not seeing enough detail to conclude that it has a clear base. Whatever. Not so long ago, the going rate for a mint Conqueror was a dime. And think how bad condition needs to be these days for most selllers to grade any marble as less than NM+.
Again, it's not about that one marble. It's an epidemic.
I should be glad that my commons are now worth so much. Maybe they'll still be going for numbers like that when I'm ready to divest.
