1955 Armour Coin Brooklyn Dodgers Edwin "Duke" Snider found in $1 box lot

I recently bought a $1 box lot at a local estate auction and found many neat "smalls" including this one within the box. This coin was a give-away from Armour Hot Dogs in 1955. I caught my collecting fever with baseball cards in 1980 at the age of eight.
The last photo is the actual box I paid $1 for, still to this day as I bought it home.
