who do I call..how do I get it listed as a recognised variety?

Just got my 1917-S in the mail today for my year set and as I studied my new acquisition to my amazement I found some odd things about it.Most notably was a raised area which looks like a ribbon across the neck.I have had a few clashed-die coins from collecting 3 cent nickels and this is not that...neither is it a die-break..there are no cracks and misplaced metal, this is a well developed RAISED ribbon.Any ideas on whom I should call or to whom I should submit this to?The extra ribbon is prominent when holding it, I hope it shows well in this photo...by the way, I searched{partially} through Heritage auction archives of mint state 1917-S buffs and haven't seen another yet..a one of a kind?..what would be cooler a missing leg{3-legged 1937-D} or an extra ribbon from the braid?!!! getting caried away now..anyhow..help please..never had an error/variety like this one...
