Well this brings up a good point.
While I agree that there are probably quite a few of these to be found if we look, we have to be somewhat careful.
The problem is we've now introduced a selection bias by actually looking for this exact variety. Yes we found 3 more but to be fair we should really ask for people to look for every possible variety of 1810EM and count how many One Kunas show up.
My 1810EM data set was reasonably unbiased. It was built before we started looking for this variety; when I did look I found *roughly* 1 example in a 100 coins. Scarce in my opinion. I suspect that's actually a reasonable ratio. So I would still say they're *relatively* scarce, though perhaps not absolutely scarce.
Best,
Steve
