This is the supplement to the Encyclopedia of the Modern Elongated reference book for elongated coins rolled between 1978 - 1995. It has a numbering system for each engraver/roller. For example, Dottie Dow's coins were numbered DOW-327...DOW-506 and Chester Rogers' were numbered ROG-177...600.
Most collectors refer to this book as Rosato's Supplement so I suggest the Numista code be ROS-S.
