Appraisal help '55 Johnston Cookies

[ekWI]

Could someone give me some guidance on where I should go to get an appraisal done on Sets 1, 2 and 3 of the 1955 Johnston Cookie Milwaukee Braves cards?

Not being well-versed in collecting and not knowing much about card value, I thought you guys would be a better starting point.

I found all three sets behind a false wall in my home during some demolition for a remodel. I thought it was a pretty neat find. In particular, there is a Hank Aaron card in one of the sets that I saw recently go for (what I thought) was a nice sum on eBay.

Thanks for your help!
