So sorry to hear about your husband's health problems.
Most of the websites that offer to give you values aren't worth your time because so much depends on condition of the item. A 1888 silver dollar in good condition is worth about $20, but one in mint condition is $400. And what might look like mint condition to you and me isn't to a coin dealer. Similarly, those websites will tell you that a china faced Madame Alexander doll with brown hair from the 1940s is worth anywhere between $5 and $5,000 (because most dolls aren't worth much, but a few are really rare). I tried to use websites to price my late mother-in-law's doll collection, but the prices I found were nothing at all like what the antique stores I visited offered. The stores showed me catalogs and handouts from auctions to justify the prices, so I know that was more legitimate than a website.
If you can find the time, take some of the items to a reputable pawn store or an antiques dealer and see what they'd offer.
