Is Here A Valuable Among These Revenue Stamps?

Hi here are a few stamps from the revenue area maybe someone will find a valuable or something better!:)

If better pictures are needed please let me know

What research have you done so far, and what did you find out? We can help with the ones you are not so sure of.

Since this area is unfortunately not available in my Michel catalog, I looked through the versions on Mystic Stamp. The very first one in the top left could be a good version. Among the first 4 10-cent stamps, there might potentially be a valuable one, and the canceled 15-cent stamp could also be worth something. On the bottom right, I noticed that the 70-cent stamp could also be a valuable version, although the differences were very small.


The 30 cents on the bottom right also looked like a good version and at the bottom right the cancel looks very nice which could increase the value.

use this site to help id your items. access to a Scott specialised catalog if possible will also help.
