Both the Royal Canadian Mounted Police and the Queen Elizabeth II Coronation 1953 was manufactured by "Richards" Sheffield England. Both measure 1-7/8" closed. Fairly easy to date.
1939 New York World's Fair 1-½" closed. Cracked ice with the Perisphere and Trylon embossed on handle. Almost 80 years old.
One new on original card, and one loose Disneyland knife. 1-½" closed.
Obviously sold at Disneyland Park in Anaheim Ca. Between 1962 & 1967.
If you observe the "Disneyland" price tag affixed to the rear of the card, you will notice:
.50¢, plus .02¢ tax, total: .52¢ which equals = 4% California Sales Tax on the Dollar.
From 01/01/1962 to: 07/31/1967 Ca. Sales Tax was 4%. Prior to this date, tax was 2.5%. After this date, tax was 5.00%
It's always important to know what you don't know.
