I couldn't find a thread already out there, so if there is one, point me in that direction and I'll post on there. If not, feel free to post your favorite error/variety or show off some new acquisition. I'll kick it off with one I received recently. This is a 1955 5 Centavos from Guatemala that displays a strong tripled obverse die. This example is hindered some by the toning which makes it a little harder to see, but it was had pretty cheap and I didn't have one of these yet. And here's the reverse just for context.
