Is a DCNote valuable ?

For a number of reasons, a DCNote can be not just valuable but priceless.
Or - not a all - it depends.

Its value lies in the information it contains.
That information can be personal (memory, intention, reminder) or objective (a promise, a proof, an explanation, an advice, an instruction...), the value of that information will either rise or diminish in time.

The above is quite apart from, and in addition to, the art value of the image it represents.
However, to acquire the actual art object itself you need to go to the original site DeepCheque.Net
