I too always wonder what people do w/ their collections. Some simply store them away, or have a safe or safety deposit box. There are some sweet memorabilia rooms on here if you search. I collect HOF autos (@217/300 + future guys). Bought 5x Detolfs from Ikea. Love em. I keep the collection in a low light area (no windows/sunlight) and only turn on the LED lights when people are over. Everything is in plastic so no dust.
Here's an older pic.....currently swapping out the card cut autos for older vintage autos here and there...
