The current Agora auction (auction 59) is closing soon: http://agoraauctions.com/listing/ About twenty of the Roman imperial coins from the second and third centuries are mine. For example, this is lot 232. Please take a look at the auction. Unlike some previous Agora auctions, this one has low opening levels. One of the coins is estimated at 1/6 what I paid for it and opening below that! (I admit, I paid too much.)
