PEZ stuff to know!

How old is a particular dispenser?
You can get a vague idea of the age of a dispenser by looking at the patent number:
Patent 2.620.061 1st series issued in 1952
Patent 3.410.455 2nd series issued in 1968
Patent 3.845.882 3rd series issued in 1974
Patent 3.942.683 4th series issued in 1976
Patent 4.966.305 5th series issued in 1990
Patent numbers are commonly referred to by only the first two digits, so a 4.9 dispenser is one from the 5th series.

Dispensers changed from "footless" to "footed" in 1987, but the recent re-release of the "Regulars" are without feet. In general, if you have a 3.9 dispenser with feet, it was made after 1987. If a 3.9 dispenser is without feet, it was made before 1987. (Of course some of these were made *during* 1987, but that's difficult to determine.)

The number located on the side of the Pez dispensers indicates the country of manufacture of each Pez dispenser, as follows (with the country on the left side & the number on the right side of the dispenser):
1 = Hungary
5 = Slovenia or Yugoslavia
6 = China or Hong Kong
7 = Czechoslovakia
8 or 3 or 7 = Austria

The following acronyms are commonly used in Pez collecting:
MOC = Mint on card MIW = Mint in wrapper
MIB = Mint in bag NF = No feet
