Hi Sue, I collect vintage cocktail shakers and some other barware, My passion is the glass umbrellas which are a subset of these types of cocktail stick, I come across a few in my hunting :-)
Values I'm not sure, in the 30's USA they'd sell for about 8-25 cents each, cockerels a $ a dozen a cheap glass shaker and glass set from the same period would be 99c.
I'm not sure with imperial prices, but there's always a dealer willing to drop a zero on something, I doubt human nature has changed significantly.
