A lot of collectors don’t put more more thought into how to display their collections beyond building some custom shelving. What about your holy grails though? You can’t display your proto, your R10, or your pride and joy the same way you display your Combat and Super Mario/Duck Hunt carts.
Personally, I’ve looked at tons of options. From aluminum table top display cases to run of the mill shadow boxes. They all can work to keep your game in great condition and help show it off. All depends on the size of your item, and what sections you need to show off.
