54 & 55 tags

[rmbutcher4]

Spent a few hours this morning in the South Jersey heat with green heads dive bombing johnnymac and I but found a couple of aluminum tags. Was wondering if anyone can tell me what they are and we're used for. They both have a serial # on the top. The 54 is red and the 55 is white.

Those were used before the stickers as validation of license plates. Cool find!

What is the item in the bottom left hand corner?

Dihren, That is a dog license tag from 1976.
