Chinese temple coin?

[junkdigger]

I found these items yesterday at an old mining area in Idaho.The two Chinese coins were found along with the plain holed disc within a few feet of each other.My searching the 'net makes me think it is a temple coin.Saw one on someone's website with a design on one side.This one is plain on both sides.Anyone know anything about this?
