Picked these up yesterday in a collection and believe three are maybe Australian and one Japanese. Hope someone can shed light as to where they are from and value? First on left in picture has no embossing, next is a Olive Green embossed on front A.G.M. with 22 under, on back is 5 and some dots. next is a gray color no embossing and last is white with F.K. Made in ? think it says Japan but not sure. Thanks.
