does anyone know how to clean average dirty toned round 50's in bulk in a less labour intensive and low cost way?

help would be appreciated.

Cheers
 
I've cleaned over 200 in one go by dumping them into a big ass bowl, adding a bottle of CA and then letting them soak overnight. Drain the bowl and then dump a whole load of bicard on top.

Start mixing as if it were dough (well, it is real money ;) ), grab a bunch and rub them vigorously through your palms and then chuck 'em aside. After a quick rinse, 99% were sparkling and it only took about 10mins or so.

I think someone did actually throw them in the dishwasher but don't remember how that went.

yeah saw this video but didnt want to manually clean hundreds of coins by hand with bicarbs.
 
Can't remember if 50s have reeded edges, they are the hardest part to clean but most 50s don't have much circulation so there isn't a massive build up of dirt to remove anyway.

You might want to skip the bicarb bit, it does give them a nice shine but if you just want to remove toning then the Cloudy Ammonia might be enough.

I generally do 10 at a time, after that I get bored and my back aches!
 
When I have had some really dirty ones I do the following:

1. Get a rectangular take away container.
2. A bit of paper towel on the bottom.
3. Coins laid out flat.
4. Another piece of paper.
5. More coins.
6. Repeat 3 to 5.
7. Fill with Cloudy Ammonia.
8. Leave overnight.
9. Rinse.

I normally only layer them one deep, otherwise it is too much effort to clean them. I find if you leave them too long before processing they can go funny colours, I once put some different coins in acetone for a week and they came out wierldy discoloured, tried the same thing with bleach and they all came out black.

I have a vibrating polisher (the type you fill with steel balls and then chuck in the pieces you want polished) and I put some coins in with steel balls and cloudy ammonia. Waited until the liquid went blue and added bi-carb of soda to finish it off. Came back later and it had solidified into a matrix of blue bi carb with steel balls and crusted coins.

Took ages to clean everything up.

To be honest I think soaking them and giving them a once over with Bi carb is the short cut to cleaning them
 
I use a time machine to warp them back to their creation year and forth again to present day. Then I store them in an ice cream box.

Worse than milk spots, you'll get ice cream spots if you don't eat the ice cream first.
 
One of my last purchases were 256 90% junk coins, put about 1/3 at a time in a closed jar with silver dip, waited some hourse then picked them out in small chunks of 4-5 with some plastic grabber, rubbed them abit with a soft sponze, washed them in water.
When jar empty, next chunk, wait again some hours, same story.
Took me about an entire weekend, although in the hours waiting I didnt stare at it, I went shopping etc.
It's WORK. You don't have it with bullion but I just like those various years/countries old coins that once circulated way more than another X times a same bullion coin. Although I like kilo lunars too, but it's sometimes hard to find them in amounts of 5 on the right moment (a low spot).
For ex, if I'd buy silver now, there is only 1 lunar horse kilocoin for sale at the dealer I chosed. I had put it in my cart for a week. It disappeared yesterday and now it reappeared. Just one.
 
Just tried it on some round 50s and it worked out well:

Tried cleaning some dirtier ones I had. Still came out ok although not as good as earlier attempts with coins in better condition.

Use cloudy ammonia but try to do them in bulk like House said. I had to clean 100 and it took a long time cleaning them individually with bi carb.
 
I didn't get much benefit from the ammonia but the bicarb works wonders and only takes 20-30 seconds a coin. Great on bars too.

The ammonia doesn't clean the coins it loosens the dirt and grime.
The bi carb then cleans the loose dirt.
One doesn't work without the other
