I have your pictures, Barbara.
The mark on the bottom of your stand was used by EG Webster and Son of New York and Brooklyn, between 1859 and 1928. The 1889 scratched on the bottom of your stand may be the date or it may be some other number.
Silver plated wares have a very thin layer of silver on base metal, so they should be cleaned very gently. In fact, I can't tell if your piece has all its plating intact.
The market in silver plate is extremely soft right now. It is difficult to sell at any price.
If all the plating is intact and the bowl is in very good condition, its current retail (replacement or insurance) value is approximately $50.If you were to sell it, you could expect to get the fair market (private sale or auction) value is approximately 40% of the retail amount, or $20, depending on location and actual condition.
I hope this answer has been helpful to you, Barbara.
