I put together a translation of the 100 skills and the coin combinations needed for them. I didn't have the time to translate what each do, but that might be something I can work on later. I took from the Japanese wiki (http://www49.atwiki.jp/onepiecemusou/pages/59.html), so big thanks to those guys.
I haven't been able to confirm them all myself, what with work and all. But it was pretty easy to decipher. I'll be updating it more after I start getting all the coins. Let me know if you guys find any errors.
