Hello Stackers

Fat Penguin here.

If you have a bunch of tarnished, ugly and nasty 50c coins and you want them to look half way decent instead of looking like you just found them at the bottom of a garbage bin, try this product....

I have done literally hundreds of coins just rubbing them with bicarb.

Seems best to me, especially if the are really dirty
 
if you use a chemical cleaner on your coins eg Goddards silver dip, Jewellery cleaner as the OP has posted, Ammonia or even CLR which is what I use before processing bulk lots for refining, you can stop the tarnish from reforming to a large degree by neutralising with disolved bi carb in warm DISTILLED water for an hour after, rinse and dry with a clean lint free microfiber towel try not to put your mitts on them after this process, the more clean silver is, the easier it will tarnish as the cleaned surface responds to the salts in your skin and will readily re oxidise.
 
I used aluminum foil with bicarb and boiling water first. That got a lot of them very clean but didnt work on some of them. This cleaner has a little basket in the container and I just left the coins in there, 4 at a time, some took a minute, others 5 or more.
Ill see if they tarnish again in a week or so.

Its not mine, so I dont now where its available, but i did see it on lloyds onine i think, it was dirt cheap too, like $20 for 3.
 
I have had success to some extent with the aluminium foil/bi-carb/boiling water but it has its limitations.

Good for removing tarnish, bad at removing dirt.

Only works on coins with a high silver content, worked well with pre 45 predec, didn't work well with post 46 pre dec, sort of worked with 1066 50 cents but I got better cleaning with other methods.

You can run a small current from a battery across the coin and it improves the cleaning but really not worth the effort.

Surely, it is necessary to do. Unfortunately, it is not too simple, as it seems to be. That is why it is better to ask assistance from the professionals. And make sure the result is better then you countered earlier.
 
That is what I do with all my 66 Rounds.
Cloudy Ammonia and then Bi-Carb.

Cleans up a treat and then store them in Tubes.
21 to a Tube = 7ozs

Have come across a few that had retained some original lustre before putting them through the cloudy ammonia and Bi-Carb.
However, I am not fussed with them as I don't collect the 50's for Numismatic value. Purely the Silver content only.

Now that is the best way to get them, if you can. :):):)
They are really Numismatic. Not your everyday 66 Round.
Unfortunately, I get mine through the normal channels and alot are pretty dirty
and need a good scrub.

what about those untrasonic cleaners that seemed to be popular for cleaning glasses and jewellrey a few years ago?
 
Might try some non-numi pre-decimal coins in a tub of salt and vinegar mix, shaken, not stirred of course. Will soak in cloudy ammonia first and try salt and vinegar shake instead of bi-carb rubbing. Works well on small nuggets to remove grease, dirt and impurities.
