This is about NGC slabs specifically. Ever notice how the dash in the serial number will usually appear closer to the last three digits? Well that if the first of the three digits is a 1? In that case, the dash would appear closer to the last number of the invoice number (first seven digits). But what if the last of the seven digits is a 1 and the first of the three digits is a 1? Then you have a centered dash! Just thought i'd share.
