Sorry, was meaning to update this a while back but life got in the way.

So I ordered one Krugerrand on 15 Feb, arrived via UPS on 20 Feb. Checked it out with calipers and electronic scales and the measurements checked out. Not exact but close enough (there is some variance I understand).

I also ordered one of those coin checkers from goldcoinbalance dot com (they take Bitcoin as payment too) though it arrived much later and the coin checks out- passes all three tests for diameter, thickness and weight.

Being my first gold coin purchase ever in my life, I was a bit weary, but short of actually taking a filing off and subjecting it to an acid test, I think I have done all that can be reasonably done to test it and am happy with the coin.
