You don’t say how big the bowl is. As a rough guide I suggest an approximate value of double scrap value (sterling silver scrap is currently about £30 (GBP) per 100 grams).

Any way of knowing the value as a piece and not scrap or is that how it is always valued?
Check Ebay’s “Sold” listings to see if you can find something similar which has actually sold to a buyer.
