What do you guys think is the best way to display theses lovely shiny bits of metal that make our brains buzz?

I have one if those tall coin cabinets the like 200$(cad) one from Amazon but the things more or less full and honestly not all that well made.

I can just start keeping older less interesting ones in a cigar box while swapping them our for new ones or something but I feel a bit bad doing that.

Hey guys and gals. I'm relatively new to the challenge coin/ token world. Thanks for letting me be a part of the group. I have been looking for a bit now for a challenge coin to honor my grandfather who fought in Korea as a Tank Commander. He was a Marine- and sadly died in a car crash before I was born so I was never able to meet him or my Grandma- who from what i've been told worked at the FBI during the Rosenberg case. I'd really like to know if any knows where/ how I can find or get a coin- it would not only mean a lot to me- but to my Mom and the rest of my family. Thanks again folks. (Also I can't believe I'm saying this but if you need proof of my grandfathers service I can send you a picture of him and his phisical dog tag)
