Other than a reprise of Topol's "Tradition!", is there any good reason why we cannot use a delineated (semi-colon ; pipe | or something else) format to set prices in silver AND bloodscrip AND ethereal scrip AND general tickets AND blackscrip AND ....

"sell vaalorn sword 999999999 silver | 900000 blood | 9000000 eth | 9876543210 gen | 123456789 black"

And let anyone who can cough up any given one, pay in the format of their choice....
