A bid has been made for $.023 for an item listed as costing $200. What does this mean?

Be more specific by providing an item number.

Most likely it is auction format with a buy it now price.

If you want to buy it for $200 you can do so by clicking on the buy it now button.

Or you can take your chance and bid on it.

When the bidding reaches a certain percentage of the buy it now price the option to buy it now will go away.

  Selling Formats are explained here.

That depends on the meaning of "costing". 

Many items are re-sold at prices lower than they were originally purchased for.  

It is unusual to see a price that includes a fraction of a cent ( 2 1/3 cents?)

Bid a nickel. Fill your boots.

BTW--- what is the shipping cost?
