Doug noted an unsold Salonina of Alexandria in the Pecumen sale which had an estimate of 100 euros and an opening bid of 80 euros. Take a look at this similar coin which arrived yesterday from a vcoins dealer. The cost, including shipping , was $40. I think this one was priced low, but the occasional availability of comparable fixed-price coins well below the auction's opening level may explain why the auction coin went unsold.
