Whoa! Obviously I didn't go to that Bible Study!
Amazing that he collected so-o-o-o many and she didn't realize the monetary value of them. (I am sure she realized the sentimental value to him while he was alive if they dedicated a whole room to them.)
I have known many that one's sentimental collection was worth $$$$ but the surviving spouse could of cared less because they resented the collection so much (bone of contention over the years). Then there are those that try to retain the collection and pass it down - realizing the sentimental values over the monetary!
Hopefully it helps her in her senior years!
