Things go better with Coke®.

1930s Coca-Cola® Aluminum Whistle Thimble.
US$75.00; 6 bids, starting at US$10.00.
16 August 2007.

Another example of U.S. Patent No. 2092942. The first example sold for US$42.00. Usually collectibles with appeal to more than one kind of collector--say Coca-Cola® collectors and thimble collectors--will go a little higher than usual because of the increased competition among bidders.
