These
post cards are from a successor to a series issued for use by cambists
(a fancy word for money changers). Today foreign currency exchange rates
are available widely in print and online, but 100 years ago, people
were on their own when it came to exchanging kroners or marks for pounds
or pesetas. This
situation gave rise to a series of post cards, produced by a German
businessman named Hugo Semmler. His cards show embossed images of
then-current circulating base metal, silver and gold coins, with a handy exchange-rate chart showing comparable values for common currencies.
