Set of Four Mini Goblets

Hello. We picked up a set of four mini-goblets at the thrift store for $6, assuming they were steel or another non-precious metal. When we got home we found they cleaned up beautifully with silver polish. But we can find no marks at all, except for what might be the number 3 in the design.

They weigh 10 oz each and stand 4" tall. There are (for lack of a better term) forge lines on the sides which makes it seem like there was an outer layer applied with the design.

Any information would be appreciated.

Thanks!
