Coins in a Bowl is super similar to something I heard indie rock dude Phil Elverum discussing recently on a podcast because touring produces too much paper money (merch table, etc.) and boredom. The game is called Wad Lord. It seems like the horrifying, high stakes version of Coins in a Bowl, plus someone is required to wear a fake beard (the titular Wad Lord).

From the guy himself:

This is not a game that can be played on the internet. It's called Wad Lord because it's about the WAD. The core of the game is the period after the Lord has assembled the Wad and passes it around to all the players. Each player has the opportunity to examine the Wad, smelling it, squeezing it, looking at it from all angles, weighing it, etc. A good Wad Lord will have made a Wad that doesn't reveal too much, but just titillating enough to give some hints. Ideally it is held together by a rubber band or a paperclip. (Incidentally, it's also not a game that can be played with non-US currency as different colored/sized bills would reveal too much.)

To clarify, game play goes like this:
-Players submit concealed US bills to the Wad Lord and announce HOW MANY bills they are submitting, keeping a mental note of their submitted amount.
-The Wad Lord goes off somewhere and assembles the Wad. (The Lord can throw some twists here by putting a 20 or a 100 on the outside of the wad, if available.)
-The total quantity of bills is announced.
-Players one by one get to examine the Wad, under the watchful eyes of the Lord and all opponents. They are allowed to do anything to the Wad besides disassemble it. Weight and smell and taste are informative factors that have come into play.
-Players write their guess on a small scrap of paper face down in front of them.
-Guesses are revealed.
-The Wad Lord (as dramatically as possible) opens the Wad and counts it out on the ground with everyone yelling and weeping as their guess is surpassed.
-Whoever is closest (over, under, doesn't matter) gets ALL THE MONEY.

(Split Wads do happen. Once I was exactly the same number off from another player, him over, me under, and we split the Wad 50/50.)

variations:
Wild Wad is what's described above. No limit, high rollers encouraged, raw and dangerous.
Limit Wad is just that: some pre-chosen submission limit. This version is not as good.

This game comes from the ultra-real world of DIY punk show merch table vinyl trafficking where Wads of cash are common. It's meant to be played late at night when people are cleaning up after some calamity (like a punk show) and only 1 or 3 rounds played. It's not sustainable for a long evening of friendly gaming. It's fast and high-stakes and eliminates people quickly. Much like real life or Monopoly or Settlers, it favors the ultra-wealthy, as long as they are willing to risk their 100s.

My favorite Wad Lord games have been with my friend who looks like a hobo wanderer but frequently has 100 dollar bills on him (under-the-table construction work). His appearance is misleading and he uses this fact to his advantage, throwing in 2 or 3 hundred dollars and winning Wads. Of course you can only do this trick once, so that's why this game is so well-suited to the itinerant world of the touring musician. New town every day, new faces, new unknown Wads.
