Thanks, Roger.
I did not feel your posts were negative. Sorry if my replies might have implied that.
It looks like a Dennison hinge,
and there was a mostly full package of Dennison hinges in another box.
I told the seller that these were considered valuable these days, and he suggested I pay $25 for the package of hinges!
I recall I have seen them sell for $10-20 on
ebay.
I have seen stamps and albums in other collections wrecked by staining from Crystal Mounts; fortunately not in this one.
It looks like the collection was put into storage in about 1965, as those were the latest stamps.
Ultimately, not being able to look at the backs gives me an excuse to offer less, I suppose.
I should have mentioned that I don't mind stamps with faults in my collection.
It makes the rarer issues more affordable.
I realize they will be difficult to sell.
Most of the higher catalog value stamps in my collection (like my #119) have
faults that were disclosed when I bought them at a discount.
I realize that many collectors here would not want to see a stamp like this in
their collection. That is completely understandable.
