Doesn't look like it is worth much if it is this type:
Vintage Set of Oneida Community, Tudor Plate Silverware, Flatware--47 Pieces | eBay
If the 'plate' in the description means silver plated, then there is very little silver in the 'silverware'.
When silver was double and triple the current price, I sold some to a company that melted it down. They would only take real 'sterling' silver. After subtracting the 10% of weight that was not real silver and their 10% commission, it was funny how little a set was worth. Seemed a shame to melt it down.
An additional problem is that 'the young people' don't really want real silverware. It has gone the way of china sets and things like that.
Do let us know what you find out about your set.
