@bart, thanks for the added information!

I have the full set of 20F, 50F, and 100F Luxembourg coins in my horse-themed collection. They are some of my favorites. The one I posted was my last acquisition of the series, graded MS66 by NGC. By today's standards, they were minted in small numbers. Each was released in 100,000 pieces. The 100F comes in two varieties -- 98,000 were minted with the designers name on the reverse and 2,000 were minted without the designers name. My example 100F (shown below) is the lower-mintage version, and graded MS66 by
PCGS.
Here is my 100F version (similar design):


Thanks for all of the nice comments everyone! These are a couple of my favorites!
