The 1785 VERMONTENSIUM is a spelling variant of the 1785 Landscape Type Vermont Coppers (the other two spelling varieties are VERMONTS and VERMONTIS). Three different die varieties (Ryder 6, 7, and 8) make up the VERMONTENSIUM sub-type. Ryder 6 and 7 are relatively common, while the Ryder 8 is a bit scarce. Thus, the VERMONTENSIUM is the most common of the three 1785 spelling variants.
In spite of how "common" the VERMONTENSIUM is, it is very difficult to find high-grade examples, mostly because of poor surfaces, sub-par planchet quality, excessive wear, or any or all of the preceding. A couple of low-end Mint State examples are known, but no Gems are known. Also, no VERMONTENSIUMs are known with more than a tiny fraction of original red color.
