Hi
Collectors in Great Britain might remember Green Shield and Co-op
trading stamps. It has been reported that the first trading stamp was
"The Blue Trading Stamp" from Great Britain about 1880. In the US, it
has been reported that the first trading stamps were used by the
Schuster's Department Store in Malwaukee, Wisconson in 1891. But I have
a stamp booklet from Dewey Trading Stamps (Troy, New York) that states
"established 1872".
As to how many different trading stamps there were, I recorded
about 10,000 different from over 4500 different names in 1999 and did
not have much information on the many thousands from Europe.
