The Lord Baltimore coin set consisted of four coins, three silver types and one copper type.
On the obverse (front) of the coins is a bust of Lord Baltimore looking left.
The 1659 coins were from England for an experiment of circulation.
There is writing around the front Lord Baltimore image of these coins that reads "Caecilius, Dns: Terrae-Mariae" (Cecil Lord of Mary's Land).

On the back side of the silver coins is an escutcheon with the Baltimore arms (lozenge shield with a coronet on top).
Lord Baltimore's shilling silver coin has the Roman numerals "XII" to the right and left.
The sixpence silver coin has "VI" and the groat silver coin has a "IV" to indicate fourpence.
The shilling is 0.925 pure silver and weighs 66 grains.
The Maryland sixpence silver coin is the same quality and weighs 34 grains.
The shilling and sixpence are just under an inch in diameter.
The Maryland groat silver coin came in two varieties with a small and large portrait and shield.
It weighs 25 grains and is about a half inch in diameter.

The Lord Baltimore penny copper coin was similar to the silver coins with the main difference being the back side.
The reverse side of the copper penny is a duke's coronet crown with two pennons flying in the center and the writing around this image of "Denarium Terrae-Mariae" (Denarius of Mary’s land).
The diameter is about 13/16th of an inch, which is a size between that of the Lord Baltimore groat and sixpence coins, and it weighs 57.5 grains.
