While
Saint George is indeed a widely revered saint, especially in the Slavic lands, this coin in fact shows the
Madara Rider, an early mediaeval cliff-side sculpture dating back to the earliest history of the Bulgarian people. The rider is believed to be a depiction of an early Bulgar ruler,
Khan Tervel.
The Madara Rider appears on many of the post-Communist circulating coinage denominations, and on a couple of pre-WWII coins as well.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
