Kiddish Cup

This is a very rare piece. I have been told by many other poshers that this is a fantastic piece and to not let it go easily. If anyone has any information on this, I am always willing to learn more 😁 I have no use for it and would like it to go to a good home. Stamped with an A and handcrafted in India. There is some marks inside but I think with a good cleaning, most will come off. I just do not have the proper cleanings to do so. I have been told these are made from sterling silver but I cannot say 100% as I am far from an expert on this type of stuff. I do know its vintage and I cannot find another that is exact. It is very solid and has weight to it (please keep.in mind when bundeling with other items, especially fragile items)
