Value will most likely go down but that is life...check out the value of your new car when you drove it off the lot. The collector world has changed since the Williams era. 20 years ago they made 20K pins in a run but 99.9999% of them went to operators and into service. Alot of them died or took a beating in the line of duty so there are few "mint" examples. Hence they are collectible now. There were very few home collectors...fast forward 20 years and now we are older with some spending cash trying to relive our youth. We buy NIB games that will most likely never go in service so there will be plenty of minty games for most of the future collectors...this will increase supply and hold prices in line. Same thing happens when the Franklin Mint offers their crap....they never appreciate because everyone keeps them in a glass case. But people think they will appreciate and be rare in the future like that 100 year old statue that is a real survivor.

Buy a pin:
First to play and enjoy...
Second to "hope" it holds it value
Third to "pray" is appreciates

edwinpblue....you kinda replied to me on the "fourth" option but then lost me on the rest of your post. Who are you referring to?
