This caused me to go to my office the next day and get the pennies in order.
Here is the 8th decade (1979-1988) and you will note that
1982 is the high year here
though the gasket seems to be holding things in place with the balls to help.
Decades 6 (1959-68) and 7 (1969-78)
have this balance and we end with a final picture
of the 8th decade to inspire the sculptor to machine decades 9 and 10.
