The single most important book on the coinage of Patraos isn't a scholarly monograph - it's an auction catalogue. Sotheby & Co.'s Catalogue of the Paeonian Hoard, being Coins in Gold and Silver of the Kings of Macedon and Silver of the Independent Kingdom of Paeonia, sold in London on 16 April 1969, is the reference collectors and dealers still cite by lot number today. A cardcover catalogue of 575 lots illustrated across 9 plates, it remains the best reference for the Paeonian kings Lykkeios and Patraos.

Because the 1968 hoard concentrated so many Patraos tetradrachms in one place, cataloguing them effectively meant sorting by dies, so Sotheby’s ended up doing the work a dedicated corpus normally would. It also explains why these coins exist on the market at all. Before the hoard came to market, coins of Lykkeios and Patraos were genuinely rare. In fact, most Patraos tetradrachms today came out of the hoard and were sold during this sale.
