I would suggest grand processions of parade scale. Trumpeters, jugglers, tumblers, fire-breathers, elephants and camels, colorful banners, minstrels, wagons of food to be given to the poor, wagons of extra coppers and silvers to be tossed to the poor, jewel encrusted saddles, all of this to announce the party's entrance into town, be it large or small.
Or you can raise an army and lay siege to the capitol of Whereverstan. Who made him king? I didn't vote for him. It's about time Grumblesnort the Gnome was king!
My favorite idea, however, is the construction of a large and very secure vault to keep the gold in, and then to swim in the afore mentioned piles of gold.
(all things I would do before buying a business that required my character to sit around 'managing' all the time or risk monetary loss)
