I know this is supposed to be a joke but... businesses have pushed for this the other way around in the past, asking for a new coin to raise prices.

> The Coca-Cola Company sought ways to increase the five cent price, even approaching the U.S. Treasury Department in 1953 to ask that they mint a 7.5 cent coin. [https://en.wikipedia.org/wiki/Fixed_price_of_Coca-Cola_from_...]

The wikipedia article says that this was specifically the price of a 6.5oz Coke.

The obvious way to raise the price by 50% is to cut the amount by a third, selling 4.33oz Cokes.

https://www.reddit.com/r/BottleDigging/comments/1kng6aq/coca... suggests that Coca-Cola was comfortable producing bottles in several different sizes.

Now, a 4 1/3 oz Coke is obviously too small to be worth bothering with. But that's also true of a 6 1/2 oz Coke. These sizes seem more like something you dispense with an eyedropper than something you drink. A normal can is 12 oz! Who'd want to buy a six-ounce beverage?

You can address both problems at once by doubling the price and increasing the volume all the way up to 8.67 oz.

When I was a kid, most sodas had a short can size of 8oz available, good for "lunches" and similar.

Funny story, Coca Cola just announced thin 7.5oz cans last month, to be available in January.

Shrinkflation is often done by phasing out an old size, often by jacking up the price first to aid the sales of the "family size" version on its way out, and then introducing a "New" size that's just a bit smaller.
