Examine the weight carefully. Check for a C signature cane - this could make a very big diffrence to its value. Typically a weight like this would be worth £200-£400, but with a signature cane that value would double.
It looks like a later macedoine or scrambled Clichy paperweight. As already stated a Clichy rose cane effectively identifies the weight (although Clichy-type canes do rarely occur in Baccarat and early American weights)
