Any help with value would be amazing!

I know nothing about the Chalmers card, but when you search for "2014/15 nba hoops blue parallel" on ebay, you get an array of offers. For example, a blue parallel of Vince Carter can be had for $3.99 including shipping. My guess is that Mr. Chalmers' value would probably be less than Mr. Carter's.

As for the Pujol's, again, ebay can be your friend. A Chrome Trout numbered to #5 sold for $600, so you know you'll be less than that. A 2021 Topps Clearly Authentic Yordan Alvarez 1986 Throwback Red #’d 27/50 autographed is up at $250 buy it now. I really don't know, but maybe your Pujol's would be less than this as well. If it was me, I'd put it on ebay with a $500 or best offer and see what happens. Any hits over $250, I'd take in a heartbeat.

I found this possible comp under sold listings:
