Back from a one-week trip in Tokyo. I went to Nakano and luckily found the Mandarake shop dedicated to the Kinnikuman stuff, with tons of Kinkeshi (definitely something worth seeing). I couldn't resist and as a newbie in this line, I took a huge bag of 200+ Kinkeshi.
Today I started the identification thanks to the boards but I noticed on some figures that something was unusual, I assume some are bootlegs (fakes) but for some I have some doubts so I need your help !
I have classfied these figures in 4 types :
1. The ones with the Y/S N T copyright but which look not genuine:

2. The ones with the copyright which slighlty appears or partially appears :


3. The ones with no copyright (almost sure these are fakes)


4. The ones with a copyright written in Kanji


Thank you in advance for your help !!!
