Nebraska issued a Bicentennial themed plate for 1976. The
number on the left side of the dot on the plate is a county code number. In
the case of the plate on the left, 10 is for Platte County. The plates were
made of aluminum, shown on the left, and galvanized steel, shown on the right.
The 10-HS61 is a very late issued plate and, if issued at all, would have
come out about 1981. 10-K307 has yearly expiration stickers stacked up to
the year 1981.
1976 Nebraska plate issued in Madison County with grey coated
back.
Counties 21 (Scotts Bluff) and 59 (Sarpy) stacked the
county codes on their plates. I assume the black on blue month sticker on
the plate on the right indicates the month of expiration.
In 1975, expiration tabs for 1977 were issued. The month
of expiration is shown by the number. In this case, February, 1977. There were
no 1976 expirations, and the 1976 base would not have been used without a 1977
or beyond sticker.

51 prefix is for Harlan County.
