Newspaper Stamps Real Or Fake?

I showed these 2 to someone who thought the 10c was probably fake but the 25c might be ok.

Anyone else have an opinion?

From Doc Pepper's study of forgeries, the 10-cent is probably a forgery of type IV-A which has these characteristics:
White flaw below second "P" of approved (the forgery was created from a photo of a real stamp from plate position #5 which has this flaw), a white flaw after the "S" in newspapers, a dot near the bottom of the P in Postage, a small dot near the bottom of T in ten. The size of the forgery is 49x93 mm versus 51x95 for the genuine. Also the genuine is perf 12, and the forgery IV-A is perf 11, 11.5, or 12.5

The 25-cent might also be a forgery type IV-A described with these characteristics: "D" in "AND" touches line below, white mark running down from right side of the tablet containing "twenty five cents". I cannot tell from your pictures whether these details match the description of the forgery versus some real stamps from Siegel PowerSearch. The perforations of the forgery IV-A are also perf 11, 11.5, or 12.5 versus perf 12 for the genuine. "NATIONAL BANK NOTE COMPANY" is crisp and easily readable at the bottom of the genuine.

So first check the perfs. If close to 12, better chance that it is real.

The fastest way to tell is to look at the National Banknote imprint at the bottom. On genuine stamps it's very sharp and clear. On fakes it runs from broken up and smudged to non existent.

Zebra - ding ding ding, we have a winner, or in this case a loser. I see all the dots except the one by the P in Postage, and it is perf 11, so fake.
The 25c is perf 12.

revcollector - I am aware of the imprint as the first thing to look at, but in this case, the 10c was only slightly less clear tan the 10c and I've seen far les readable ones on fakes, so I wasn't sure.

Second thing to check is the embossing. Most fakes are not embossed, and the ones that are, the embossing does not match the design. It is usually half the numeral low.

the 10c fails that test, the 25c passes
