Hello and good morning,
I really need some help identifying my collection as to what's Cracker Jack and what's not.
Also, I'm wondering about the materials they are made from, such as celluloid and bakelite.
Thanks

Hiya, and welcome to the forums.

The girl with the bucket and the butcher are Cracker Jack prizes.
Those two belong in a set of 12, you can see more of them here -> http://www.c-carey-cloud.com/cracker-jack/Plastic/Plastic-Standing-Characters-1/

The very small prizes are most likely from gumball machines, many of the larger items are Cracker Jack prizes. I'll let other, more knowledgeable people, talk about them.

The Alphabet Dangles are also Cracker Jack prizes, more about them here -> http://www.crackerjackcollectors.com/Jeffrey_Maxwell/alphadang/dangles.html

Thank you very much for your help. I'll definitely come to chat again.

Several sources (people older than me) have told me that many of the plastic "gum" charms like those you have with strings on them also came on bread wrappers back in the day when bakeries started broadly marketing sliced bread. But of course the primary source was bulk vending machines, and even dime stores sold them on individual cards and cards of ten charms.
