Is there a standard coin thickness?

[+Doctor A]

I have a friend who's working with me on making a display stand for my geocoins, that will be kind of similar to the "challenge" coin display stands that I see. Anyway, I need to let him know what thickness to make the slot where the coins will sit in and that got me to wondering- is there a standard geocoin thickness? All of my coins "feel" or "seem" to be about the same thickness, but in woodworking, I know that precision is necessary and I want to be sure that the slot is big enough to accommodate any standard coins but not too big that it won't hold them fairly straight up. Anyone know? Thanks!

3 to 3.5 MM typically

Some recent coins have reached 4mm.

3mm is the "standard" but coins range from 2mm to 4mm, or more if 3D.

Please post a picture of the finished display when you have the coins loaded, will you? I would love to see it. I've been looking for a good quality display box to place inside of a curio-cabinet I've had my eye on.

Will do! Mine is also going to go in a curio cabinet that I already own, so probably will be something similar to what you'd want or need. I'm excited about trying to come up with a design and I know he'll do a great job of turning my thoughts into a wonderful display stand.

 

Thanks everyone for the info!

ThePetersTrio had asked me to post a picture of the geocoin display stand that my friend made for me, so here it is. It's a similar design to many of the coin displays, but done in a size to fit the shelves on my specific curio cabinet and painted to my tastes!
