The 1969 S Doubled Die Obverse 1 is probably the second rarest ddo known after the 1958 ddo 1. Only a few dozen exist. PCGS has certified 2 MS 64 Red examples. http://www.lincolncentresource.com/doubledies/1969Sddo1.html
Sorry, no it isn't. memorize the BE in liberty, the multiple overlap makes them easy to see. If you look at the bottom of the 6 in the date of yours, you can see the flattened 'doubled' area that is mechanical doubling or as also called 'strike doubling'.
