The use of coinage as currency in the Mazes dates as far back as [[History of the Mazes|Era 3]]. The [[Languages|Old Tongue]] word for "coins" or "currency" was '''''Paramil''''', which was derived from ''Param'', a noun which meant "value", in the monetary sense, and ''Il'', a noun which meant "metal". Thus, ''Paramil'' could be transliterated translated to "valuable metal". At the time, there were only four types of coins; copper (''Gusil'', translit. "red metal"), silver (''Silil'', translit. "silver(-colored) metal"), gold (''Limil'', translit. "golden(-colored) metal"), and platinum (''Zeril'', translit. "white metal").
During Era 5, with the introduction of the modern languages, such as Common and Youkai, currency was briefly known as the '''Para-Dollar'''; a portmanteau of "Param" and the word "Dollar", which was invented by Jonas Dolar in [[Calendar#Era system|E5-123]], when he founded the Neo Khazrun bank. After his death in E5-157, the "Para-Dollar" name was shortened to '''Parallar''', and has been used ever since.
As time passed and technological levels increased, metallurgical advances made it possible to work with a wider range of materials; namely, alloys, which made it possible to have many different intermediate denominations between the four original coin types. Eight new coin types, most made out of various alloys, were introduced during Era 6. The very first brass coin was minted on Nonama 9, E6-99 (09/09/99 on calendars at the time), using cartridge brass as the base material. See [[Parallar#Brass coins|this section]] for the full story.

Although platinum coins are not as popular, they are the most efficient way to transport value using coins, with a value per weight unit of 5000; higher than any other coin type in the game.
They are most commonly nicknamed ''Plats'', though in a similar manner as to the letter G and gold coins, the letter P is sometimes also used as a shorthand for "500 Parallars".
They are made out of fine platinum, with a purity of 99.9% (.999 grade).
