For collecting purposes, some friends and I are wondering about the type of plastics used in older game sleeves. I've been informed that PVC (corrosive to precious NES games) was the official plastic of the 1980's. So, I'm wondering if I should move my five NWC carts to a different bin*.
And this is where you clever folks come in

*Author does not actually own 5 NWC's, but he very well could. Besides, my copy of SMB3 is probably more fun anyway
