Help Identify This Per-Fin & Any Value? Rarity?

I found US per fin EC but I can't find per fin ECI which is on my stamp. Anyone else know anything?

Please show us a shot of the back. I do not think this perfin reads ECI - the I is a K maybe ? Take a scan or photo on a black background for clarity

It is EK/C
Being off-center, the legs of the K of the adjacent punch are at the left side. Visualize them together.
Eastman Kodak Company.
Note also the Rochester, NY oval cancel.

I am nit at home right now, will be in a few hours and will do it then. It's definitely not a K. It is an I. I could not find E C I on US Perfins which is strange.

The Rochester, NY cancel makes it more likely it's an Eastman Kodak perfin. Certainly not definitive, but does influence.

How's this for more influence? Here's what you get when you place a copy of the stamp next to itself to complete the pattern:

Sigh. And this is why one must examine the entire stamp, not just one side of it.

Good catch, John.

hunter3rd...I believe John is correct.
I enhanced your stamp to see the alignment of the letters.
If centering counts, I would also say it was a "K"...
No expert here..Just my opinion.

All you have to do is look at the first post - the two arms of the "K" are on the left side of the stamp

Peter

Peter is correct..Here is your left side of your stamp brought to the right side of your stamp

There seems to be an echo here.

A little information on "It's definitely not a K" ... when you are a bit more into perfins, you discover the most weired things perforated. One letter inverted and almost exactly on the other holes, even two different perforations on one stamps are possible.

And there have been a lot of punching machines in use with broken/missing pins. So even if there is just an "I" visible, it could be something else.

For identifying take the letters that are obviously correct, and see what can fit to the vertical line -> B, D, E, F, H, K, L, M, N, P, R, T (in some cases).

Here is a wonderful example of missing letters in an Austrian perfin, that is found in 99 % incomplete.
You might think of an American company -> US/TF (last picture), but if you are very lucky, you find a stamp with the complete perforation. Then it reads -> FLUSS/HUTFB for Fluss Hutfabrik in Freiberg.
