Possible Native American Basket with Lid fine weave N.W. Coast?

I bought a number of what I think maybe authentic Native American baskets at an estate sale that also had Navajo weavings. I do not know really anything about how to determine if these are actually Native American but this one is quite finely nicely made with a tight weave and wanted to get an opinion from others. It has a lid / top with woven handle. Don't think from the SW buy MAYBE pacific N.W coast? Interior of the basket looks to have what I think is a cigarette burn. In any case and information would be greatly appreciated. Thanks much.
