First of all, what is the average price for the regular Freedom Blade? Also, I have a "do not claim" version. Is that worth much more than the regular?
Considering that the "DO NOT CLAIM" sword can be exchanged for a chest with a Snr.staff member, it's worth quite a bit more (as much as a chest).
Actually, I believe that you can't have it exchanged anymore. and if seniors still exchange it, I don't think you'll get it exchanged for the chest..
