Because why not:

Name: All that Glitters(Midas Fraud)

Nen Type: Manipulation(?), Conjuration

Description: The user first shrouds their hands in a field of Nen, causing a black mark to appear on their palms, after which they will touch an object of their choosing. Once they have touched said object, a small mark will manifest onto it(the same as on their hand), akin to Hisoka's texture surprise, and will be clad in a field of Nen. As soon as this happens, anyone who looks upon the object will see it as immensely more valuable than it actually is, and will be unaware of any trickery whatsoever, the only hint of which would be the small symbol hidden with In. It could, for instance, turn pebbles off of the ground into diamonds to be sold at a high price to jewelry peddlers, scrap paper would appear as £50 notes, pennies would look like gold coins etc. The mark can be placed on things of all sizes, ranging from pebbles to houses, but as the objects are covered in a field of Nen, larger objects will require more Nen to cover them. After the required amount of aura has been met, the object can be clad in even more aura to make it seem more valuable. However, if Gyo is used on the object and the mark is seen, the illusion will stop taking effect and the user will see the object at its true worth. If the mark is damaged in anyway, the same thing will happen, with the exception that the illusion will be broken for all those who look at the object; even non Nen users.

Limitations:

1) The mark will disappear after three days.

2) After a mark has expired, another one cannot be placed on that object again(this also means that a mark can be rubbed off before it expires, allowing the user to place another "fresh" mark on the object instead).
