Nowadays, people may tell you that they can duplicate an item and make you rich. That is not possible anymore, but this Runescape glitch was in the past! Before, there was a minor bug in Jagex’s code, which a few people found out and took advantage of. This bug allowed any non-stackable item to be duplicated, which meant these people could use the identification code of expensive items and make as many as they wanted. Soon enough, the magenta partyhat (people called them pink) moved from being the most expensive partyhat to the cheapest partyhat. The magenta partyhat moved from about 5 million gold to only 200k gold in a matter of days and caused a big dent in the economy. Apparently, these newly duplicated items looked exactly like the original, so Jagex couldn’t tell who had the real partyhats and who didn’t. Now to this day, the magenta partyhats are now of a darker shade and are still the cheapest partyhat because there are a lot more of them than the other partyhats.
