R8 - Only 3 pieces known. Struck in copper with a plain edge. "Both sides showcase magnificent ice-blue patina with golden-olive accents. A rarity with perhaps just three pieces known." Ex: The Bob R. Simpson Collection, Part III
CAC - Low R.6 - struck in 100% tin. Ex: Massachusetts Historical Society and Appleton Collection (Stack's, 5/1973), lot 325; Harry Bass Collection, Part I (Bowers and Merena, 5/1999), lot 1082; David Cassel Collection / ANA Signature (Heritage, 8/2015), lot 5944.

CAC - Low R.6 - Struck in tin (mostly) with a plain edge. The stated composition of this piece is: 97% tine and 3% copper. The tin surfaces are bright and virtually undiminished by toning. The strike is strong throughout and there are a number of lint marks impressed into the reverse, debris that obviously adhered to the die by static electricity after the die was wiped by the coiner.
CAC - Low R.7 - Struck in copper-nickel alloy with a reeded edge. Was in an NGC holder - Judd-641A Unique. Years ago SEM-EDX testing was conducted by Ledoux & Company on NGC certificate number 581886-002. That testing revealed the composition of this piece as: 76% copper, 23% nickel, 0.3% cobalt, 0.2% iron, and 0.1% silicon. "The fields show the expected die polishing marks, and they are exceptionally mirrored. Additionally, the devices display significant mint frost, giving the coin considerable field-device contrast on each side. Just a hint of pale golden-rose toning is present across each side. The devices are fully struck in all areas."
Low R.7 - Struck in nickel with a reeded edge with about half a dozen known. This is the finest certified. A Postage Currency related pattern, dated 1868. "This is a brightly mirrored piece that shows only slight golden toning on each side." Ex. Bob R. Simpson Collection, Part IV, The Distinguished Gentleman of the O.C. Collection.
