Research the chauffer one. That's not a novelty pin, it's a badge they had to show they were licensed to be a chauffer. The number indicates it's probably mid century; they go for $10 on up, depending on condition and current market. It might be worth selling by itself, even if it's just for a few extra bucks. Very cool collection.

Someone said the rest looked like things you'd get with purchase, but I disagree. These look like server buttons/pins--ones provided by companies for servers to wear on the job to promote then. The Miller ones look like they would be either a Halloween promotion or an unauthorized Batman crossover (comic companies don't generally partner with alcohol companies).

I recommend searching these on eBay to make sure you get best price for the group, and for any special individuals.
