Sentence:  I am still inclined to think the London auctioneers can be trusted, but I have little faith in the Germans. If you put a $20 <WSD>limit bid</WSD> by accident on a $1 autograph at a German auction, you are pretty sure to get it at $20. Like some other auctioneers, if they know your limit they will supply any amount of competition, honest or otherwise. 
Meaning of the word marked with <WSD> tags:  An offer to buy in an auction for any value up to a specified maximum.
