These 4 tea glass holders are not easily identifiable.  Some of the workmanship seems primitive: yet the repousse medallion on the front of each tea glass holder is beautifully crafted. I am not sure about the metal.  They were heavily tarnished, and I have removed only some of the tarnish with silver polish.  I bought them to make tea lights but decided that removing the handles might damage them. 2 ½” in diameter, 3 inches tall.  Very lovely old pieces.
