Digby Antiques (Wiltshire) has dated this piece to the 19th Century.

Not entirely sure which Prince of Wales this refers to, it could refer to George IV or equally to Edward V11 when they held the title, as both were known to be fond of gambling.
It is faceted all around 12 sides, it is in excellent order with only a couple of very minor chips to the base.
