Hiya Mike
First - nice pins - and I've seen some really cool and incredible pins in the past few pages.
I don't collect pins - tho I like them - just don't want to sway too far from my current "focus."
A favorite of mine - is a complete "team" set of pins - that most likely were sold at ball parks in the 50s.
What makes this one more cool? The original cardboard backing.
Based on the Braves and Nationals pin? I would date this set from 1953 to 1955.
Pins are 3/4" and in really nice shape.
