Anytime buddy, I do like the border around the circumference of the coin itself it gives it a more solid look compared to the previous releases.
Also I was expecting a much smaller coin and like it's actual size too.
Agreed. The 0.5 BTC coins are also quite big in comparison with their big brother, the 1 BTC. 39mm vs 43mm, and 16g vs 20g of Titanium. They are about half the thickness though (obviously).
They are very well made. I could not find a flaw on the few I looked at.
Overall, I am very happy with them. Sure others will be too
