Is there anyone on here that has the capability to engrave serial numbers as small as what you would find on a really high priced diamond? I would really like to start having my quarters engraved with a serial number system so as to identify it as an original. Any Engravers help out there would be fantastic! below are some links with pics

for something that small it might be difficult to find someone.
Marking metal means using a pretty high powered laser, or perhaps
a fiber laser. But most machines within our reach don't have the kind
of resolution needed to make markings that small. The type of lasers
most of us use have an effective resolution of around 200dpi (even
though they will run at higher settings, the beam size is about 1/200th
of an inch across) That's not fine enough for what you want.
I'd give Bruce Boone a PM and see if he's got any advice for you. I know
he's got a laser that will work on metals, but not sure how small it can
go.
 
Since you are casting them, why not cast a nice looking serial number plate as well. I could see a number band around the tube or a nice looking dog tag (you could even shape it like the state).

Are you trying to reduce the size of the numbers below what is readily visible? If you just want them marked really small Is .5mm to large. I have a set of hand stamps that are 1mm tall but they offer them in .5mm as well. .5mm is about .020 tall

You could buy a set and do it yourself.

The problem with doing it by hand is gonna be the fact that I will risk breaking the quarter from the pounding. These things are 1/3 the thickness of a standard quarter, so they bend easily. This is why I think a laser my work better. I think .5mm is feasible, my next obstacle is where to engrave? Do I leave a flat section (that is typically cut out) specific for the serial number?

Maybe a drop down below the word"State" for the serial number.

I like the idea of putting a tag in the pr you could print it small like on a decal and even hide it under the clip so it doesnt take away from the rest of the pen
 
If you stamp them before slicing, they shouldn't break. You could also get a custom logo stamp and wouldn't have to number them.
 
Seamus,Bruce's idea of a custom logo stamp might save you the expense of having to ship each one out, the engravers charge and shipping back and has he suggested stamping before slicing the quarter solves the problem of doing damage.
 
I use the 1mm size stamps on Silver. You dont hammer the stamps you only roll them around in a small circle and the pressure from your fingers will inset the stamp. I measured a quarter and the one I have measures .67 the .5mm would be a third the thickness of the quarter. THis company also makes "logo" and other custom stamps that size.
 
well if .5mm to 1mm is acceptable, you could always cast them, finish
the pen and laser the serial number under the clip. If that's the case, then
most anyone with a laser can help you with that. But you might want
to do a color fill of the engraving and then seal it with CA. That would
also allow you to do a custom logo if it is small enough.
 
I have a machine that will be here in a few days that can absolutely do it, but I don't know how to use it. I do know it is capable of engraving numbers or letters so small you need a magnifier to see it. Once I figure out how it runs, I'll have to try throwing some coins at it. I imagine the most complicated thing is getting the bit to the right location on the coin, but once that's figured out, I see no reason why you can't have your logo and/or your ID number there. I could no doubt be able to cut the entire coin out for you too without even sanding the backside away..or make a completely new coin from metal as thin as you want! :smile-big:
