A sealed game and a console with a rechargeable battery are two risks. One is cardboard. The other can leak. In the overview Security for collectors you separate the two.
What time does
Sun fades the cardboard. A battery that stays in the device leaks and eats the contacts. You take rechargeable packs and batteries out of devices in storage. What is sealed stays sealed. Discs and cartridges sit dry, not in the window.
When someone comes
Consoles and small cartridges go easily, a shelf full of cases more slowly. The expensive sealed pieces and the one rare console do not stand by the door. Proof on the list, box uncrushed.
The folder
System, title, sealed or loose, with original packaging or without, proof. Device and game are two lines.
