Finally found that this mark and several variations of it was used between 1930 and 1965 so it is one of the more modern marks !! From the style of your item (I think it is a small vase) or could be a spooner !! I think it was made late in that period !!
As to value,, no real way to know what someone would pay for it !! My opinion is about $20. USD or less !!
