Thank you for your responses. They have been very helpful.
After I calmed down and I studied it a bit, I think I found the issue.
My max bid was 6201.99
The winning bid was 6102.00.
The increments at that point were 100.00 each.
I can only conclude that had I placed my max bid higher by .01, I penny more, I might have one. I say might because it's always possible the winning bidder had actually placed a higher bid than that.
Thanks again for your input!
