1 Cent Franklin Green - 318?

I got this stamp at an antique store and wondered if it is a 318. THoughts?

No. The cancel is 1907, the coils were not issued until 1908.

I just took a look in my Scott Specialized and there's a warning about coil stamps of 1908 that says: "Warning! Imperforate stamps are known fradulently perforated to resemble coil stamps and part-perforate varieties. Fully perforated stamps and booklet stamps also are known with perforations fraudulently trimmed off to resemble coil stamps."

Given this, revcollector, are you saying this stamp/cover is fradulent? As in, it has to be either a #300 or #314 that's been altered in some way?

(I'm trying to understand classic US stamps better, so forgive me if there's an obvious answer I'm missing.)

It might not have originally been fraudulent. The user might have simply cut the stamp from a multiple. Or it might be a natural top straight edge that someone later did cut fraudulently at the bottom. It's a trimmed 300, not a 314. Either way it is not a genuine coil.

No, the cancel is fake added to make it appear to be tied to cover. The date stamp is probably authentic.
This stamp was altered, then applied to cover, fake cancel added, in the hope of making it appear to look like a unique item. (No known 318's used, or on cover).

I had written a lengthy reply to each of ClassicPhilatelist's points, but I think it best to take a different approach.

While I agree this stamp has an extremely high probability of being a trimmed 300 giving the illusion of being a 318, it would be good to have scans of the entire card as well as a higher resolution scan of just the stamp. This is just as much a postal history item as a stamp item and it deserves conclusions drawn from fuller examination.

StampCrazy,
When you upload images, you need to give each file a unique name before uploading.

You are so right - thanks I was answering my other post. I really appreciate you straightening me up. This is what I meant to upload. See this is confusing. Why do some of these look like this on the side. I know these 2 are a different stamp but how do they have a cut and perf at the same time? Is that an error or what?

These stamps were printed in sheets of 400 stamps then cut into 4 panes of 100 each. The straight edge you see with the green ink is what is referred to as a "cut line". Stamps like yours are from the edge where the sheet was cut.

i understand, thanks
