Since Brett Favre announced his retirement, Number Four items have been hot, but don't burned. The Better Business Bureau is warning fans that phony Favre memorabilia is circulating. Randall Hoth, Wisconsin Better Business Bureau President, says for “autographed” items look for a certificate of authenticity. He says there are number of organizations that offer these. Hoth also says look for a hologram in the corner of an autographed picture. Many reputable dealers will have a numbered hologram that can be tracked in a database.
If you want to buy from sites like Ebay, he warns of sellers with numerous items at “rock bottom prices.” It's also important not to rely solely on the seller's online reputation. “The reputation has to include delivery on time and refunds, but the authentic part of that may not be the case,” Hoth explains.
The Better Business Bureau also has a listing of dealers and their reliability at bbb.org.
