Values are terribly subjective, and highly dependent on geographical location and method of sale (i.e. bricks and mortar auction house, online auction, yard sale, dealing direct with local dealers, selling in an antiques centre will all have varying achievable ceiling prices). As such, many, if not most, of the members on this site will, understandably, shy away from giving values rather than raise any false hopes or be made to feel bad (or morally liable) if their estimates turn out to be too enthusiastic.
