Thank you gents for all your help. I guess I ought to explain myself a little better. In like manner to the laser engraving that Apple is happy to do on your iPod or Phone or whatever, I would like to accomplish that upon the reverse of my coin.
Here is the obverse of the coin, representing the solar system. Pick a date, and I can place the planets in their proper location.
The design is there, it’s minted in through the classic process of cutting a die and pressing the metal between the two halves. This is the reverse, representing the phases of the moon. In the blank space on the back is where I would like to be able to relay to people the message they desire for whomever they have these coins made.
It’s simple, at some point I’d like to mess with logos, pictures, designs, but all that I need at the moment is simple text, which isn’t so simple from what I gather. Essentially just etching a dog tag or medical bracelet, on a flat surface.
I do have a fixture to hold my coins in place, got a couple of these off eBay for $15 bucks and I will have a spacer below the coin to not allow the pegs to be an issue with spacing and clearances.
