I recently purchases this microscope from amazon, and started looking at everything I can get my hands on at 40-150x.

I wonder how long until someone tries an xray microscope (or whatever they are called) to see the private key underneath.

I'm a radiology resident and back when BitBills came out, I took a low kV radiograph of it to see if I could bring out any detail...I was hoping the ink was made from the oxide of some metal...no luck. The BitBill was glorified laminated paper, which would be much more susceptible to xray hacking than a metal coin. I strongly doubt anyone will find success with a Casascius coin.

Looking forward to it.

You mean they can't?

If only I could have not had the first one come out "CASACIUS" (misspelled) in the largest fine print (partly visible in one of the photos above - first photo, 11 o'clock position).

We actually did two designs and I picked through design number 1 with a fine tooth comb for detail, then went with design number 2 without having done the same. I noticed it instantly once I took some light to the then-newly finished holograms. Series 2 fixes that.

Let's talk governance, lipstick, and pigs.

That looks like a dot-matrix process. I was wondering about that.

I recently purchases this microscope from amazon, and started looking at everything I can get my hands on at 40-150x. One such thing was the hologram on the back of a casascius physical Bitcoin.

I believe this is actually only 10x and 40x, but 40x was enough to see what I didn't know was even there: four rings of "CASASCIUS" just inside where it says "ORIGINAL" on the coin. Looking at it by eye, I can barely identify the bigger outer ring, and definitely can't identify the smaller three inner rings. This is impressive: casascius really put a lot of quality into these holographic films!
