Scott 832 A304 ?

I looked; no hinge, glue on just the stamps ... and obviously, there aren't four... so where does that leave this?

really nice plate numbers
couldn't say anything else..

As long as we're on Scott #832, let's learn together.

The arrow line pair is not a standard collecting format. It will be worth more than 2 plate number singles, though.

I did want to mention something else, though, Barb. I noticed that several of the stamps were in what we call "corner mounts". Those are the triangular shaped thingies at 2 or 4 corners of the stamp. They are usually used on larger pieces, such as covers or S/S's. The problem with corner mounts is that they easily damage the corners of stamps and S/S by pressing a bend into them. Covers tend to be a bit stiffer/sturdier, so are not as badly affected. In the pic you showed in this thread, the stamp has a backing, so the corner mount creases have probably been prevented. However...

...the other problem with corner mounts is that since the entire stamp is not evenly covered, sometimes a noticeable discoloration appears between what is covered by the corner mount and what is not.

I realize that the stamps have been in those corner mounts for at least 55+ years. You may want to take a few out and see if there has been any damage to the stamp. While the damage sounds trivial, it defaults to a major defect. I know quite a few collectors who would never consider buying a stamp with corner mount damage, although they would readily buy stamps with thins and creases!?

Bottom line -- I wouldn't keep them in corner mounts, damaged or not.

Just my opinion.

So... now what? Can I put showgard mounts on acid paper? ... Pull the blocks out of the corners and put in glassine?

Better news is that much of what I looked at today is in great shape.

How much work does one put into stuff you probably want to sell?

This is becoming a full time job... maybe I can get brain dump from all you guys, and just open a stamp store?

Yes, you can put Showgards on acidic paper. The mount backing serves as a barrier.

My personal practice is to remove stamps from corner mounts. More often than not, there is already damage to the stamp. Condition is a big factor when it comes to actual sale price. Stamps that have corner mount damage often sell only in the 10%-20% range, unless it is a major premium item.

Glad to read that they are in great shape. Obviously, your grandfather was very careful.

Grandpa was careful, but it also probably goes to fact that no one has opened them in a VERY long time too. They just sat in their fireproof box.
