i have never bought off of him either, but i wouldn't say that the coins were over prised, all the pennies seem to be at or just under the catalauge price...you cant count it with some coins; he has a BU full lustre 1806 penny for sale for £225, £50 over the unc. coin value, but this is because of its rarity, it doesn't say extremely rare, but a BU full lustre penny that is over 175 years old is extremely rare to come by...
