Does this Hallmark look familiar to anyone?

Hello Everyone

New member here.  I had a friend who has asked me to sell this item from his Mother's estate.  She thought it had some value.  The hallmark is either an M or a W.  Does it look familiar to anyone?  Thank you in advance.

No, not offhand. The value in the market is in those pieces that are almost instantly recognisable by their style, and the mark would be known to every serious collector instantly' Looks a competently decorated piece, which from the base photo looks like Raku. Which is a medium that does not have much value in it at the moment.
             But value is decided by the marketplace. Your best bet is to try it on Ebay. Probably trying to sell  it through a traditional auctioneers might well lose you money!

Value depends on who the potter is, and until it’s identified I’m afraid it has little or no value. Even if you do find the potter’s name it still may not have any value - plenty of raku pieces selling for just a few dollars on eBay.
I’m afraid I don’t recognise the mark. Most of our members are based in the U.K.; you may have more luck on some of the Studio pottery groups on Facebook

Thank you for your reply. Greatly appreciated
