Frank Robinson on bidding early in his second-price mail sales:
  Hi,
  Reminder: My Auction 78 closes in a week, Tuesday, May 4, 11 PM
  Eastern Time -- over 500 lots of ancient & early coins, mostly nice
  material, nearly all unreserved.
  
  Find the catalog, with good user-friendly pictures, at: http://
  www.fsrcoin.com/a.html
  
  PLEASE don't hold back from bidding early. It's really your best
  strategy to put in your top bid early -- that will help you buy the
  coin at the best possible price (bids are reduced to just above the
  next highest) -- and remember, you can always check back later and
  raise your bid if necessary.
  
  Best regards
