Dipping will certainly make it look more like AU58

 Zonad, I can't see the Obverse very well due to the toning, however, did you look at the "V" in Victoria to confirm whether it was an A/V Variety or not? Glenn  |

It definitely isn't :)...no doubled N in CANADA..
I think I got a 1872 A/V 25c from...wait for it...
CENTSLES...graded by NNC (National Numismatic Certification) ;)...LOL
Seriously though...
Just hoping ICCS will agree with me on it :)
Also finally found the elusive 1885 5/3 25c...which apparently exists only in legends of unicorns and fairies...
Now if only my darn USB microscope would finally arrive so I can get some pics out! :)

Another 1872H. To dip, or sell? Once I get my album working.   |

dipping anything less than an EF coin is pointless. In my opinion, the only reason to dip a coin is to expose the luster that may be hiding underneath. If you dip that 1872 it will only turn to a lifeless grey exposing more of the scratches and gouges. Toning on a vg-vf only helps a coin in my opinion.

the worst thing about dipping, is leaving the coin unattended. Each second it is dipped unmonitored is too long, and even when it's pulled out by tweezers, its still considered still dipped until fully washed down with tap water. also the coin must be slightly swirled while dipped to allow for the chemical cleaning process to be uniform on all areas and both sided I always try to remember its the dirt I want off, not the tone or patina of the coin. and for that its seconds and half seconds of intense look at your coin with tweezers ready  a good dip is called "restoration"  while a bad dip goes under so many names finally... good luck !  try the bullion coins first |

If dipping in thiourea, 5 minutes should be plenty, rinse with water & then you are back to blast white. We are talking 5 minutes to get zonad's AU58 back to blast white. If you are just starting to get those ugly black spots on your silver, then a quick touchup with a Q-tip dipped in solution will do the trick.

Any thoughts on using baking soda and water in an aluminum pan? If you've never heard of it, google it. People use this technique to 'polish' their silverwear to remove the tarnish. It causes a natural chemical reaction to turn the silver oxide on the surface back into silver. Will this change the surface of the coin the same as the other dipping solutions?

What exactly is thiourea? 5 minutes seeems kind of long.
I use a silver jewlery cleaner and its no more than 5 seconds and then right under fast flowing water out of the tap. If its EF or AU I'll dry it with a soft cloth. If its MS I'll hold it by the edges and fan it in the air to dry.

When I have dipped coins in the past, they are coins that already are unc they just need a nudge. I don't get them graded afterwards I just keep them. A coin that is not Unc in my mind is not worth dipping. The nice XF 1872 quarter should remain as is - once dipped, it will highlight the problems. The other 1872 quarter would be a waste of time to dip unless you were doing it just for practice as this coin is already close to being bullion value anyway.

We are talking an endless argument with No real answer. A skilled coin "conserver" can make an incredible amount of money restoring the right coins , whilst an idiot can destroy great coins by wrongly cleaning them. Check out NCS a division of NGC. Myself I love pretty toned coins with wonderful eye appeal........technical grade not extremely important, the artwork is!
