Currency

Gold Pieces (abbreviated GP) are the standard currency used in Tibia. The coins can be made of either gold, platinum, or crystal. Therefore, 100 crystal coins are equal to one million (1,000,000) gp!

Alternatively, you may see amounts followed by the letter k. This likely derives from the latin kilo-, meaning "thousand" (1,000). For example "5k" means "5,000 gp" (equal to 50 platinum coins). The notation "1kk" is sometimes used to mean "1,000,000 gp" (100 crystal coins).

(Note: Amounts in the "one million" range are typically only mentioned in the context of selling extremely rare items or as a payment demanded in lieu of being hunted.)

You can exchange your coins at any Bank NPC around Tibia.

Inflation basically never occurs in the Tibian worlds. Instead, equipment tends to become cheaper and cheaper over time, while the value of runes usually remains approximately constant (a slight rise in price can be noticed on very old worlds).
