German Salt-Glazed 1/2 Liter Stein, No Pewter (Now)

It may have had a pewter lid; there is the small cavity in its grip near the rim for anchoring one, but no evidence remaining of one being attached. Its 6" high, ~2 3/4" rim, ~3 1/2" base, shallowly concave; weight is ~19 oz. The graphic either side of the grip base seems deco, but I'm not at all sure about that. Inside that grip base is 1900...whether it's significant as far as dating the stein I'll leave to y'alls expertise. Is this anything out of the ordinary?
It was Dad's, an' he thought it had been his mother's; neither of them were German. Thanks for lookin'!
