Yes, I have bought some (1) from his auction. had not problems and hsi shipping is less than Heritage.
I have purchased coins from David Lawrence. As RLM pointed out, the S&H is cheaper and I have never had any problems. However, the photos are really bad IMO. With a site that big, they really need to work on the photos. Heritage has pulled far ahead in that category, which IMO, is one of the most important.
YES - Paul is correct, the pictures are not very good and do not necessarily show the true color of the coin. At the same time I have never had a problem either - and I check over there often.
