Cursed Coins

A player in the group I'm in keeps autistically searching for coins wherever he goes. What mild curses could be found on a coin?
Current idea:
>The Paranoid Plunderer's Pence
>Whoever possesses this coin will see humanoid shapes flicker by in shadowy corners barely in sight, and will always commonly feel his gear/coinpurse as being lighter than it used to be.
More extreme curses welcome for discussion, though I'm mainly trying to find minor ones.

How about we talk about the reason why you find it necessary to passive-aggressively punish your player? Is it bogging down the game? Or is he playing a character quirk? Have you tried asking them what the deal is with this behavior?

It doesn't seem like that bad or annoying a quirk, and results in a bit of emergent inventive and not too serious fun on the DM's part. It will make the quirk feel like a real thing and adds some depth and color to the game.

Dig that stick of yours out of your ass.

>Dig that stick of yours out of your ass.
Seconded

When player counts his gold it seems like he has more than he really does and when the time comes to pay, he always misses a few coins.

When the player flips a coin, it's always the cursed one if he didn't get rid of it and it always makes him lose/chooses the worst alternative (examples : what path should we take ? The one where the big snakes are hiding.)

Just off the top of my head, a coin that keeps dropping everytime he picks it up.

See how many times he goes for it, thinking that it's something special since you keep narrating the drop

Just start giving out clipped half coppers

If I can add my 2 cents in hehehe , I think makes a fair point. It's a weird quirk that could lead to interesting plot-hooks or just fun moments for role play. In fact it seems far stranger for the GM to just blatantly ignore it. like, it's a obvious quirk, why are you not pointing it out? are you scared to say anything? or do anything with it? Do you believe this would upset the player? how sensitive do you believe the player's feelings are? how sensitive are you to assume that it would upset the player?

back to the original topic: Perhaps instead of the coin itself being directly cursed, it could be a mcguffin for other indirect problems, like a rival adventurer using the PC's love of coins to bait him into a trap to slow the party down, or even into a deadly dungeon the BBEG wanted the loot from but wanted the PC's to do the dangerous parts. Or the PC finds a coin belonging to an autistic dragon that is going to hunt them down to the ends of the earth to get it's favorite coin back.

>Advocate maybe talking to your players about problems you have with their playstyle instead of throwing around in-game punishments
>WOW DUDE LAWL GET STICK OUT OF BUTT

Yeah, alright.

The Autistic Token
>you have a strong desire to autistically search for coins
That will show him.

OP wasn't even talking about having any problems.
