Hi My name is ***** ***** I would be happy to help with your question.
(1) Regarding your 1950s Hull Pottery giraffe planter/vase, you are right, most of these do not have gold enamel highlights, however there are a few that are indeed embellished in this way.
For instance, this one has a gold trimmed midrib to the foliage, as well as the hooves and other details on the giraffe. Here's another with gold on both the foliage and the giraffe, and another with just gold hooves and none on the foliage.
I don't think that the gold embellished ones are any more collectible than the plain, they seem to sell on line (like the standard ones) in the range of $15 - $30 and has a book value (full retail value) of $60 for replacement and insurance purposes.
(2) As regards ***** ***** & Floyd giraffe bookends, in this case your gold version is indeed rare, but not unique.
Fitz & Floyd produced a number of these wild animals in white blanc de chine as bookends and some do indeed have gold hooves and horns, such as this bighorn .
As far as value is concerned, the most sought after bookends by Fitz & Floyd are the equestrian horse jumping ones which sell on line for $200 - $300.
Your giraffes are almost as popular, ranging in value from $60 - $90 per pair, and probably towards the higher end for your golden-hoofed and horned ones. Retail/replacement value $200.
I do hope this helps!
