Rep Of Korea: A Couple Of Questions

Question 1:

According to Scott there were three issues circa 1884 that were never placed into circulation. Don't know if these issues had a name, but the set includes 25, 50, and 100 mon values.

According to Scott, counterfeits exist. What are the common spotting tips between genuine and counterfeit issues?

Question 2:

Scott 966 (A502). Review of multiple copies reveals a number of shade varieties. However, Scott assigns a single issue number. Do other catalogues address this issue differently?

TIA.

There is a nice post in this forum;

As for forgeries, they are numerous and made by Kamigata and possibly Wada in Japan
The forgeries are duller, different perforation, generally not well centered, and usually have a 5 ring fake cancel not used in Korea.
Most used early Korea stamps are fakes.
Later I will post samples - I have about 2 dozen

Thank you both for your responses. The depth of knowledge provided by SCF members continues to impress.

Perf 12: Scanned through the link you provided. Wow. Looks to be the definitive discussion of the topic. Much to learn.

SForgCa: Thank you for posting the three "Moon" issues. Those are the stamps to which I was referring. My examples are also uncirculated (not cancelled).
