Glad it was helpful Earl! The oldest cards tend to be worth the most. 60+ boxes is a ton of cards to go through… some serious collecting going on! Bound to be some valuable cards somewhere in that collection!

Unfortunately a lot of the cards produced in the 90’s aren’t worth that much. Are your daughter’s cards organized in any way (like best ones in hard cases) or just in a big pile? I’d start by looking up the ones in cases, then I’d pull a few examples for each year/ brand… for example 1990 Upper Deck, 1990 Fleer, and 1989 Topps… you get the idea. Type them into the search box on https://mavin.io and you’ll get results for what individual cards, packs of cards, complete sets, etc. for that brand and year. You can sort the results to see what the highest cards sell for. The results are things that have actually sold, so you could expect to sell your cards for the same price… assuming you have the time to sell them online! Good luck!
