Would be almost exactly like the pins that you would get in real life. Could possibly come with a display case or stand. Would be great for showing off what you have in game in real life! Nice for display to pimp up your OG CS setup or to show to your friends that happen to also be CS players and make them extremely jealous.

Also, they could be a blind-box sort of thing like the CS pins that were sold at Katowice, but that might not be so good for people who only want to buy the pins in-game. Like I said, a possibility.

Also, the ones that aren't coins and are more like trophies (like the pick-em challenge trophies for example) could be implemented as well, but obviously wouldn't be coins. Could be a similar size to fit in with your collection of coins and could also come with a display case or stand.
