If you reincarnate do the "Death Barter" exploit, which basically involves sending out all your SS on barter actions prior to drinking the reincarnation potion. Once you reincarnate afterwards you will have to wait for the timer on those SS to finish, hence have 0 command points until they complete (assuming those SS were made permanent, if not then you will have your default 2 CP), but you will receive the silver in the next life. Don forget to have over the ptp protected limit (800 default i think) of silver on hand to reap the benefits.
