Our History and Values

The oldest name in stamp auctioneering in the world
Established in 1898


Zinopoulos and Sons Stamp Shop

Plumridge & Co – Established in 1898.

Founded by Mr H.W. Plumridge, the business started as a stamp shop based in the West End of London. Sometime before the First World War,  we moved to larger premises with our own auction rooms. The new premises were located in the Strand which at the time, was the heart of Philatily. Our stamp auctions , which at its peak were held twice a week, continued through both wars. In more recent times, the office was moved to Adam Street and then St Martins Court where auctions were held in nearby hotels including the Strand Palace Hotel. More recently we, like many others, have relocated to premises on the outskirts of London. Our current premises are easily accessible by rail and road. At the present time, we are holding regular quarterly auctions.
