Quoted from schudel5:Depends.
Games where features were removed on production games the samples might hold a higher premium. Some it's just cosmetic artwork changes like your game. There are a certain collector that that may appeal to, others may not care.
Some sample games they found problems and changed production games for the better. Jackbot sample games have problematic lock design and was fixed on production games. Had a sample Jackbot and couldn't wait to get rid of it.
Now, prototype games might hold a higher value due to very limited production (20). Sample games they usually made a fairly sizeable quantity (200).
Agree that it depends, but seems like EM collectors hold them in higher regards.
