Nonsense. I've never been to America but never had a problem recognizing any object on a captcha (except some indistinguishable letters on letter-based captchas occasionally). Everything is obvious even if it looks somewhat different from its European counterpart. I don't know how much exactly is a nickel or a dime but it's obvious to me these are coins. Everybody I know (and most of them have never been to America) is Ok with these American captchas too. The only problems with captchas are they spy on you (Google doesn't actually check if you are a human, it checks which particular human you are) and annoy you.
