thanks for the update! One of my favorite little mods and I'd missed playing without it :)

due to the laws of supply and demand, nobody wants to pan shells cause theres loads on the sand.

Step One, must create a sense of scarcity. Shells will pan much better if the people think they're rare you see. 
Bare with me, Take as many shells as you can find and hide them on an island, stockpile em high until they're rarer than a diamond. 

Step Two,  gotta make the people think that they want them, Really want them, really Fuckin want them, hit em like Bronson, influencers product placements
featured prime time entertainment, if you haven't panned a shell, then you're just a fucking waste man

Step Three, it's monopoly, invest inside some property, Start a corporation make a logo, do it properly. 
"Shells must pan" that will be your new philosophy, Swallow all your morals, they're a poor man's quality.

Step Four, Expand, expand, expand, Clear Forests make Land, fresh blood on hands.

Step Five, why just shells? Why limit yourself?
She pans sea shells, pan oil as well!

Step Six, pan guns, pan stocks, pan diamonds, pan rocks, pan the water of a fish, pan the time of a clock.

Step Seven, press on the gas, take your foot off the brakes, then run to be the president of the United States

Eight, big smile, mate! Big Wave, that's great, Now the truth is overrated pan lies right out the gate

Nine, polarize the people, controversy is the game, it don't matter if they hate you if they all pan your name. 

Ten, The world is yours, Step out on a stage to a round of applause, 
You're a liar, a cheat, a devil, a coral.

And you pan seashells on the seashore. 

TheSapphicSeas Should work if you replace "path": "/attributes/panningDrops/@(sand|gravel)-.*/-" with "path": "/attributes/panningDrops/@(sand|gravel|sandwavy)-.*/-" in assets/shellpan/patches/shellpanning.json

TheSapphicSeas thanks for alerting! Working right up!

As of 1.21 it seems this is no longer working :(

Hopefully this still works!

Using in 1.20 for a islands play through as a method of getting lime. Thanks a bunch works great.

It should work well, since it is a simple content mod SunshineFaith

Will this mod still work?   1.19.3/4  I love collecting things

This mod is a great idea! I never once thought of the lovely shells back when I tried making a panning mod haha :) Great job! ^_^

Due to the laws of supply and demand

No one wants to by shells when there's loads on the sand

Yskar You get more seashells than vanilla, because Vanilla do not give you shells in the panning loot table in the first place.

And making options for specific types of sand would be quite a challenge, one that I fear is actually impossible, at least with my skill and time.

I didn't understand, so using this mod you get more or less sheashells than vanilla?
How about an option to determine the seashells would just (or mostly) drop using an SPECIFIC type of sand?

Great idea! I'm gonna use it sooo much (and have my house cluttered with twice the amount of shells)

LazyViking didn't knew it :p

Its chance per seashell is 1 in 500 per seashell panned in Muddy Soil (8% success rate per Binomial Distribution), so I think that it is still balanced. Should I lower the chances?

you can get this in the Wild Farming - Revival mod when paning Muddy gravel

Sir Pun-A-Lot

Very clever mod name lol
