VDB on the reverse appears doubled

I recently picked up a 1909 VBB Lincoln Cent and after close inspection concerning the VDB it show doubling on each of the letters. The coin was found in a circulated roll of coins and brought to me where upon I purchased the coin at a reasonable price. I then looked the coin over in detail and found this error. I am wondering if this is common or uncommon. I have not sent the coin out to NGC as yet but plan on doing so as soon as I get more information on the coin. If you have any infor please e-mail me at dlgcoins@gmail.com Thanks
