They aren't anything I'm familiar with. I agree they look older. I'd need much better pictures to do any real research on them though, no offense meant. I'd have to be able to read several of the numbers and that they'd be face up on their highest number while reading them.

Instead of taking a bunch of new pictures, it would be easier since you have them in your possession to Check Dice Collector yourself and see if you can come up with a manufacturer there. Here's a link

DiceCollector.com - How do you identify who made a die?

See if that helps and comment back here, I'm curious to know too. Your's don't match up with any of my old sets that I've checked so far.

I appreciate the help! I will upload a few more pics as well. There are a few "markings." These are smaller than the Holmes set dice. I put them side by side.

The d10 with a "cut" on the top/bottom might be an indication that they could be a set by Armory...  I have a set of them at home and will check with mine.

Yep, these are the dice that came with the Moldvay or Cook sets. There was a d12. They came un-inked in a bag with a crayon. http://www.athenopolis.net/2018/02/tsr- ... basic.html
