Do These Have Any Values, What Should I Look For?

I am sure if they were very valued I wouldn't have these many they have been purchased over 10 years ago, since then they may have had some values in them, what do you reckon?...thanks

It is virtually impossible to pick out anything 'special' in the images you posted. As a group, the value is in the hours of enjoyment (or pain depending upon your perspective) of going through them and identifying the stamps.

To some this is hours of enjoyment finding cancels, caps on 2's, all different stuff. For others, this is torture.

These are 2c small banknotes, 2c 1st bureaus, 2c Washington definitives and 2c 4th Bureaus, all with possible varieties.

It depends upon what you want to do.

If you like stamp varieties, each of these has different types, plate flaws, and cancels.

Could be hours of fun detective work. Most likely nearly all will have negligible monetary value, but you may find some better stamps.

If you want to sell them without the work, I recommend grouping them within each type (groups of 10, 25, 100, etc.), and fully scanning the front/back so that the prospective buyers can do their detective work. Start the listings at 0.01 or 0.99 or similar starting point.

I note one of them was placed inside a black mount at some point. I'd look at that one first.

There almost seems to be a theme going on with postmarks perhaps.
