I found some interesting stuff.

There are three categories of Saints' relics:

First Class - part of a Saint's body

Second Class - something that the Saint possessed and used

Third Class - something that the Saint is known to have touched or made physical contact with.

There are no relics from Joan's burning. Immediately after her burning the Earl of Winchester ordered that her ashes and remains be consigned to the Seine river. I guess he figured "no relics = no martyr".
The only known first class relic is one of her hairs which she attached to the wax seal of one of her letters. Its location is unknown.

A number articles of Joan's clothing (second class relics) were tossed into bonfires during the French Revolution. God knows why... mob rage I guess.

There are nine surviving letters which bear her signature, as well as a number of other third class relics.

A topic of great controversy is the location of Joan's armor. It is felt by experts that its authenticity could be readily confirmed, as the injuries she sustained in battle are well documented.
Best prospects for its location are Burgundy in France and Luxembourg.
