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 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 fusion 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 name Para-Dollar was shortened to '''Parallar''', and remained in use 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 of which were 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.
