Revision
Revision. A second or subsequent design replacing a prior design not considered satisfactory for further reproduction. Revisions of coins occur to change designs for better wearing qualities (as lowering of lettering on the reverse of the 1913 Buffalo nickel). Revisions of medals occur for a variety of reasons:
(1) Correcting errors of design or inscription.(2) Change in sponsor's name or title.(3) Correcting mechanical errors.(4) Change of seal or trademark.(5) Addition of lettering.(6) Removal of lettering.(7) Modernizing design.(8) Reinstating medal or sponsoring program.Revisions almost always require reworking the original models or patterns and cutting new dies.
