The value of this coin can vary depending on its condition, rarity, and demand among collectors. It is recommended to have the coin appraised by a professional numismatist to determine its exact value.

ivAnother answer:Both IIII and IV stand for 4 in Roman numerals.
Presumably you mean IIII and IV not 1111 and 1V? Both IIII and IV are correct Roman numerals representing 4. IV is a simplification of IIII. Traditionally IIII is used on clocks instead of IV. The ancient Romans used IIII for 4 because they were superstitious about IV, those being the first two letters of Jupiter's name.
