What would be the value and age of this pin/pendant?

I wasn’t able to figure the Hallmark out without digging deep in my books but it does have the hopicraft Hallmark I believe they used between 1949-1961. Hoping jewelry if family sought after and depending on artist could be a huge difference in prices

I find a similar mark attributed to a Larry Pooyouma in Margaret Wright’s Hopi silver book. Says he worked silver until 1991.
