Wedgwood Ring

I’m wondering if anyone can give me a rough valuation of this wedgewood ring. Below are some posts that I placed in the ‘Identification’ section of this forum, hopefully they could help in the valuation.

A kind poster responded thus;

Wedgwood silver rings are selling on eBay for £10-£20. I notice that one very similar to yours, with the same maker and a date of 1957 failed to sell at $29 (£18 ).

Hello,

The manufacturer’s name is indeed F.A. Welch (not Welsh).

Sorry I can’t help with the other queries.
