A 300 Game Bowling Ring

This is the United States Bowling Congress, USBC 300 ring I got when I bowled my first sanctioned 300 game(one bowled in a league, or tournament) after 43 years of bowling for fun, and on leagues.
I got the 300 game on August 20th, 2013, on a senior bowling league, that I bowl in. Then I got another 3oo in February of 2015, on the same league. If I would have gotten my first 3oo, earlier, the USBC used to give a 10k gold ring with a center diamond, and you could get another diamond for every other sanctioned 300 game bowled. This 300 ring is a size 13, made of Siladium, and engraved with my name, and the date bowled, and is free. If you want a Silver, or Gold ring, there is an extra fee, for each(more for gold), and for any other sanctioned 300's, after your first. I wear the ring on a sterling chain, around my neck, instead of on my bowling hand, because it bothered my bowling, and I wear too many rings already!!!
I would really like to collect more 300 games! :^)
