Thanks for all the comments! Whether to grade or not was the big question. I don’t mind spending some money to make sure they are protected and I know what I have. And I guess these are not technically mine. They really belong to the extended family so we will see what happens. We are in no rush to get rid of them, but no one expressed interest in keeping them.
mrvster – It certainly occurred to me to try and build a St. Paul set since I was born there, but I already collect too many things and that would not be cheap!
As Matthew H noted, there is some browning on the edges where they were sitting in the album. No breaks, however. The Broughton has a small abrasion(?) to the right but it is just an area that is not glossy like the rest of the photo. No edge wear that I can see and the backs are very clean.
The album also has two boxing cabinet cards from the 1890s, a James Corbett and a John Sullivan. See photo below.
