In USA crazy's or a kid that never seen SBA dollar there often mistaken as a quarter??? but in England there been a lot 2006-+20091 pound coins counterfeited that was reported in Coin World 2 months ago??
There's been a few other threads where the police have been called to investigate a two dollar bill or a SBA... coins or currency that are not in general use and some people are not familiar with. Maybe someone was trying to spend a SLQ... that would definitely be 'suspicious', lol.
