I recently was fortunate enough to recieve (as a gift) a bottle of the Pappy Van Winkle Family reserve 23 year old bourbon

I have wanted to try this for a few years now but the cost has prohibited me from doing so,

I have a question regarding the bottling, From what I understand there are only a few thousand bottles every year (therefore the high price) the bottle I have is numbered "C14104" meaning more than 14k bottles are available?, can anyone shed some light on the numbering key to prove or disprove my assumption
