Medal identification Pierre De Coubertin

Hello,

I found this medal and I can't find any information about it. Is it real or fake medal?

I keep looking at this and kept thinking there was something very familiar its the initials under the neck (HOLL) those appear on some of my silver tourist commemorative coins/medals from Germany.
