Pennsie Pinkies were made by Penn. They are the core of a tennis ball. Good pinkies were given a coat & sent to the tennis clubs. Rejects were sent to the cities to be punished.

Pennsies were softer, and a little stickier, even though they were a bit smoother than Spaldeens (Spalding). Best for box baseball (easier to pinch & spin), punchball & other bounce sensitive games. Spaldeens were more likely to show up in stickball games (they were 5 cent cheaper).

If money was a problem, you went into the corner store & asked for an ‘egg’ ball. These were half-price off-brand (unlabeled) balls that were kinda round, kinda bouncy, and kinda ugly (not always pink).
