If you're building a stand, be sure to plan for the ability to vary the distance between camera and subject easily, and a ball mount of some sort to finely adjust camera positioning as keeping the plane of the coin and the plane of the sensor parallel is imperative. That's why Ray suggested a cheap tripod - it's a very inexpensive way to accomplish all that. I use one that cost all of $25 at Best Buy and it does everything I need.

Being a carpenter, I'm going to try make some sort of stand. For DIY /1/ The tripod thread is standardized by ISO 1222:2010 as 1/4-20, which means 1/4" diameter, with 20 threads per inch. You can easily find a matching T-Nut at the hardware store... one of those things that mail-order is nuts for, as the shipping is 2x the price of the goods. That + a small rod and you're good to go. /2/ If I DIY myself, I'm thinking about this: http://www.adorama.com/MCFRS1.html ( Amazon and others sell it too) - the photo of the back I've seen shows what looks like 2 1/4-20 so I imagine it would be easy to secure to an A-frame. -----Burton

Thanks Burton. I bought this in hopes it would attach to what ever I build and it would give me the fine adjustments that I may need, but looking at yours make me wonder if I shouldn't have went that way instead http://www.ebay.com/itm/40053972368....m1497.l2649Edited by rmc

So far this entire set up including the camera and shipping costs has cost me $366.75 Canadian.

If you end up building a stand, you will need to make it very flexible for camera height. The camera to coin distances vary over a wide range from Dollars to Dimes, and especially so for the objective (which will only have about 15mm between lens and coin). One option is to build a solid, fixed vertical for the camera that is as high as you will ever need (for Dollars) and then adjust the height of the coin with pieces of wood or build an adjustable riser to bring the coin up to the lens.

All we give up is the side-to-side adjustments and for that, well, we always have the "other macro adjuster", a/k/a fingers... And of course the beauty of DIY is you can try a couple of things and if it doesn't work, go cut some more wood and try again. I'm no finish carpenter, but with a table saw and a chop saw I figure even I can build an a-frame with a plywood gusset for attaching the rail to. Now as for a stage, I'm playing with 3D Mfg and have 'designed' this:  Which I call 'a thing' or maybe a 'coin ring'. The idea is it's a little bigger than whatever coin, has the cutouts to allow fingers to grab the coin when you are done and the shelves and outer ring to securely place the coin in a consistent position. We'll see if it works... heck, it's the 1st time I've done anything with 3D modeling let alone manufacturing, so I'll probably get a white blob of plastic and a recording of somebody laughing hysterically...

Fixed camera and spacer blocks of varying thickness depending on the coin size is a GREAT idea.
OR maybe a fine thread bolt with a foam pad standing upright...screw it in or out for adjustment

Very unlikely. It's made for walk-around macro of bugs and flowers. Best to get a pair of Jansjo LEDs and then learn how to add diffusion, etc to get what you want out of them...Ray

I will wait patiently to see the results! You might want to brush up on your image editing because that will be a learning curve...

By editing do you mean with a program like "paint"? With the crappy cameras and microscopes I have been using has given me plenty of practice in that department

Don't use paint - that's too crude. I'm cringing at the thought.
Search for Paint.net, it is a whale of a lot more powerful and free. I think the site is getpaint
net...
