davidcyclebackI have no knowledge of the inner workings or details of their auction process, but have not personally seen evidence of anything wrong. I have bid for perhaps 5 years and have had my bid maxed out, but have also had it beaten and won at price below my max bid.
MastroNet does a lot of advertising, regularly appears on the national and international news (I read about the PSA8 T206 Wagner on the BBC), and has a solid reputation, so they get a lots of bidders and lots of bidding.
