I think it has good value to it myself, provided the stress cracks are not too detrimental and can be repaired. With that Thunderbird design on it, I'd term it an early "Fred Harvey" era piece. Being that it is a spork makes it very unusual. The fact that it isn't stamped/marked is also (to me) more evidence that it is an "early" Navajo or Native American made piece. How did you determine it was .800 silver versus sterling or coin silver? .800 to me would indicate to me that it's likely a European made piece, which it's obviously not. I can see it being coin silver but not .800.
