"His total collection is probably worth about $200,000 dollars."
Captiva, if you decide to stay with him don't plan to spend that 200,000 to quickly. Unless he's had his collection appraised by an expert this is a fictional number. I have a recently deceased relative who had a 70,000 coin collection (his estimated value), we had it appraised by a professional coin dealer at 47,700, and we sold it for 35,200. There are three distinctly different numbers you are dealing with.
Basements have moisture and if this effects the quality of the cards they will lose value in a hurry. I would urge him to move them into a temprature controlled and fireproof environment immediately.

"If you love him too much and you are willing to take him as he is, then you should stop complaining."
