Pictured below is a personalized certificate in the name of Frank Showalter of Williams Corner, PA.  The certificate looks quite fancy and is printed on heavy weight paper.  However, in doing research, I found that over two million of the certificates were printed from 1898 until 1935.  Each certificate was given as a “thank you” for supporting the preservation of The Betsy Ross House in Philadelphia.  How much was given to receive this is unknown.  How many survive today?  Several are offered on eBay and the price is $15 to $100.  The Betsy Ross House website states the real value is in the fact that the owner of the certificate knows that their relative/family helped preserve the Ross House.  Added: We visited the Betsy Ross House in Philadelphia and saw one of these on the wall leading up the stairs.  I remarked to the family members that were visiting that I had one at home.  I showed it to them and they thought it was so cool!! A real piece of American History.
