The first pattern coinage authorized in the United States were actually the Nova Constellatio patterns of 1783 which were authorized by the Continental Congress.
These coins are known as follows:
1) Mark or 1000 Units which would be similar to a silver dollar. This unique coin is listed as Breen 1099 and in Taxay as EP8.
2) Quint or 500 Units which would be similar to a half dollar. Two different varieties, each unique, are known and are listed as Breen 1101-1102 and in Taxay as EP9-EP10. The one which is part of the illustrated set and the other, illustrated below courtesy of Heritage is ex Ellsworth, Garrett, Bowers & Ruddy Garrett I, Perschke, Heritage 4/13.
3) Bit or 100 Units which would be similar to a dime. Three examples are known in both plain and twin olive leave edge varities. The coins are listed as Breen 1103-1104 and in Taxay as EP11-EP12. One of the two known leaved edge coins, ex Garrett is in the collection of John J. Ford Jr., the other was sold as lot 112 of Stacks 5/91 auction. The plain edge coin was also earlier in the Garrett collection. It is now in the collection of Eric P. Newman. All three are illustrated in the Stacks 5/91 catalog.
4) 5 Units which would be similar to half cent. This unique coin was rediscovered in 1977 and is listed as Breen 1105 and is footnoted in Taxay.
An 8 unit coin is also believed to have been produced but is unverified today.
