Probably not. Extremist radio host Hal Turner - a not very credible source - has a video (link) and a post claiming otherwise:

Earlier in the week, I reported via this blog, the shipment of 800 Billion AMEROS from the USA to China. Many of you called "bullshit" on the posting, claiming it was a hoax. I now offer irrefutable proof.

Below is a video of me holding one of the actual 20 AMERO coins sent to China. Additional coins with face values of 50 and 100 AMEROS were also sent from the U.S. in addition to paper currency shipped BY the U.S. from the currency printing firm in Europe!

I didn't watch the video, but the pictures provided at the last link match this page where someone is selling "private-issue fantasy pattern coins" ("Amero"s) to collectors. That could certainly be a false front, or the coins Turner is discussing could be different, but there doesn't appear to be anything to this story.
