.1878 .925 2 shillings silver postage stamp British Transvaal Victoria circa 1878 rare postage stamp silver ingot broochA magnificent treasure I have seen none other like this brooch. This beautifully detailed silver marked era 1870s Victorian British Transvaal 2 shillings postage stamp ingot holds a right facing queen Victoria in a border of words for Transvaal Postage Two Shillings. The detailing is fantastic with the reverse of the silver ingot brooch having a border of leaves and an engraved name for Dr. P. Keller, Group 8. It is a magic little treasure.
