Coke cap confusion?

[obiwin]

Thanks for sharing these tips and the FB Group tip.

I've found the Coke Caps confusing too, so I haven't focused on these two much, and are a gaping hole in my collection that I hope to eventually fill. I was hoping someone had already cataloged all the nuances of this set, and was just waiting to stumble on it. Sounds like that day has come.


Any chance you can share some photo examples like

1. What the 3 different coverings look like? (plastic, cork, and foam?)
2. Big head vs small head variations side-by-side?
