what I noticed about this gimmick, is that it's easy to flash. I'm not a huge fan of the way Tango
made this coin. I feel there are slightly better versions. The side angle is easy to betray and
people closing inspecting the coin from the side might catch a glimpse of it. Also, the special part
of this coin doesn't look nice. There are ways to adjusting it and changing it, but they are kind of
tricky.
