Eire 2c Oa Pinsin Need Help Determining Date

These stamps are in a book of World Stamps. I have been going through the book alphabetically. So far all of the stamps are between 1889-1930. I need help figuring out exactly what I have. Thank you. The horizontal perf., one the green stamp, is 15. I cannot figure out the vertical perf. Thank you.

You need to go to the reference section of your local library and look at the Scott catalogs. Older ones may be available for checkout. The front section of any volume will tell you how to use the catalog plus has other important info. Stampworld online is useful as a listing.

Good start in identifying the stamp perf. The vertical measurement can only be perf 14 for both the 1p and 2p, but this applies to two different issues with different watermarks. What is here is minimal value but many collectors would collect each watermark type as separate stamps.

Welcome to the Forum.

The stamps you posted are part of a popular definitive series from Ireland. (Don't know why the Issues you posted would be mounted on Russian illustrations.)

Basicallly there are two series of stamps: 1922 - 23 and 1940 - 42. Both have a perforation of 15 x 14. The difference being the watermark.

The 1922 - 23 series has Scott watermark 44. Which looks like the letter "s" with a horizontal bisecting line.

The later series has Scott watermark 262. Which looks like a lower case letter "e".

While watermark fluid is one of the preferred (more common) means of determining the specific watermark, (unless the stamp is heavily canceled) you may be able to discern the watermark type by placing the stamp on a dark (contrasting) surface. Based on personal experience, this is one of the easier watermark types to discern/identify.

Cheers.

Thank you very much. I was wondering the same thing re: Russian page mounting. I'm thinking my great grandmother was losing her marbles when she assembled the collection. I was excited about the prospect of a Russian stamp from the 1920's.

I'm 98%c certain they are pre- 1940 stamps because:
1. authenticity of book copyright 1934
2. avg age of collection
3. comparing to another stamp with a cancellation date 1955.

I've attached a photo of the postmarked stamp. This one is more than likely the 1940.

The 2d coil stamp only has perfs on the horz. and a straight edge on the vert. Is this correct?

Correct for the one that is perf 15 horizontally. There is another 2p from 1934 that is perf 14 vertically and imperf horizontally. Obviously, both can be forged (badly) by trimming.

Thank you.
