Help With 1895 Korea 6A Stamp

I found a Scott Stamp & Coin Company International Junior Album in an antique mall last week that goes through 1928. The names of the countries is fascinating, especially Korea, which is spelled "Corea". One of the stamps is what looks like an 1895 Korea 5 Poon stamp as shown below. This is not my area of specialty, but it seems to me that the stamp isn't very sharp in places and that there is a green splotch beneath the second "o" in Poon.

Does anyone know whether this stamp had irregularities in the printing? When I googled the stamp, a number of the images had irregularities and similar splotches in various places. However, there was no mention of them in the Scott catalogue, but it did say that counterfeits do exist. So, does it appear that this stamp is legit or could it be a counterfeit? If so, did this stamp have any value in the late 1920's or early 1930's to warrant such a forgery?

Any help you can give would be greatly appreciated. Thanks!

Perf 12: Thank you for giving the link above. Wow! There were a lot of great examples shown.

The stamp you have is real and is the first printing of the issue.
The stamp was printed by the Andrew B. Graham Banknote and Bonds Co., of Washington, D.C.
The size is 22 x 25-1/2mm and was shipped imperforate to Japan for perforation.
Known perforations on the first issue on the 5 Poon are as follows:
10-3/4 x 11; 11-3/4; 11-3/4 x 13; 13 x 11-3/4; 11-3/4 part perf; and imperf.

The stamp was printed with a lithographic stone which was reportedly disposed of, after the Graham Company went out of business, in the Potomac River.

The first reported printing of this issue was 25 July 1895 and the 5 Poon was issued for the domestic usage. Mint issues have a strong, pale glossy gum which is often crackled.

There is a "dot" found in the SE petal of the UR flower. There are numerous stone imperfections found within the pane of 10 x 10 (sheet of 100) and I have been able to re-construct and plate full sheets of ALL four values, based on the imperfections in the stones.

EDIT:
P.S.

The forgeries were created for use on "Tourist Sheets" sold to tourists "getting off the boat" in Korea and Japan. The forgers being WADA, MIZUHARA, HONDO and several other "creators" of the time. The stamps were never used to defraud postal authorities in Korea. WHY? Because the penalty for the forgery and use of counterfeit stamps on mail in Korea was the Death Penalty! :)

Thanks Hal! That's quite a penalty - don't think I'd want to be a forger in Korea!
