Counterfeitting Underground ernie tokens[]
one day, some market in China made counterfeit versions of these tokens, which couldn't be distinguished from a real one, unless it was put under a UV light. If the real one was put under a UV light, there were patterns that are hard to replicate, while the counterfeit ones had a 'U' on it. Underground Ernie figured out what was going on though, and he put a stop to it.
