US Philippines Coins in Ten and Twenty Cents

Newbie here. I got some US Philippines Coins in Ten and Twenty Cents of various year and conditions. These are circulation coins. I was looking at the PCGS website, but many grade levels / years don't have a value. How would I go about determining the value of these coins? Should I just comb the PCGS and NGC website?

edited to add... most circulated 10 and 20 centavos are not worth enough to slab.
