Sorry, guess we were all waiting for Mairo to get back to you. Anyway, here's what My Krause says for your figures:
#1: Swiss 20 rappen 1990, cupronickel: 6.534 million - actually quite low for this type.
#2: Bahamas 1˘ 2004: no figures given.
#3: Somalia 5 shillings 2000: no figures given.
#4: Panama 1˘ 1983: 5 million. Again, a comparatively low mintage compared to other years.
#5: Panama 1˘ 2001: 160 million.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
