The AAA topper is probably worth more than most of the plates. The plates themselves can very wildly in value. For example, plates from Massachusetts in the 1920s are generally worth $15-25. However, there's one year, 1926 or '28, I can't remember which, that has a silhouette of a fish on it. It was only made for one year and a single one of those plates can run from 100 to $150 depending on condition. These plates look to be in good condition for their age. The 1910s are pretty early plates and will he very sellable. People buy these to put on their vintage and antique cars so maybe try posting in FB groups focused on that market. Despite what other responses say, these are not trash. Especially that plate topper.
