Advertised Sales
Weidemann beer signs for sale with a price provided are scarce, probably because collectibles' values fluctuate greatly depending on what collectors will pay. Occasionally, an exceptional Weidemann's vintage beer sign may appear on Internet sites or in classified ads in collector's publications. These are generally lighted signs, may include motion, and, as of 2010, are priced in the range of hundreds of dollars.
Membership Sales
A larger number of beer signs and other memorabilia are available from vendors who generally sell to other vendors. These websites and advertisements in media require the buyer to subscribe and buy a membership. While memberships are perhaps not extravagant for antique dealers, they can prohibit individual buyers from learning prices.
Auction Sales
The majority of vintage beer signs are bought and sold on auction websites. Searching for Weidemann's signs reveals a considerable number of authentic signs in various conditions. The general merchandise websites suggest a starting bid and include a time for the bidding to end, all on the Internet. Specialized collectors' auctions sell items both online and on-site during auctions. They may sell an item whenever they please and so, registering a winning bid is more difficult because buyers may be outbid from the floor.
