    Short answer, who cares? It's bullion. It will always sell for bullion value. It has absolutely no collector value at all.....

    That will ruin the coin. No doubt about it. This has been discussed at CoinTalk many times.

    Yea, that's why I wanted to ask here, cause I darn sure don't want to hurt it.
    I read something about grape oil not being as acidic, but I really know nothing about it. There seems to be a lot of people that might. Maybe Doug will pipe in and give an opinion too.

    Thanks guys, I'll just be happy with what I have. It's not that bad.

    Maybe to show you what I was talking about, I bought these 2 coins the other day for $100. The 1936-D has a nice finish, but the 1937-D is lacking a little.
    I just bought them hoping they will upgrade my set. It's been at the bank for years. I guess I'll find out next week.

    True with the corrosion but I havent mustered up the guts to do that to any of my coins. however your right corrosion is a reason I forgot about.
    thanks

    Olive oil is acidic, it will take away part of the strike. Its the same with vinegar. it does clean it up but the strikes profile diminishes.

    Agreed
    Nope please dont dip it in grape soda. Acidic is acididc it will eat at the coin regardless and cause damage.

    Beautiful coins, best of luck with upgrading the set.

    Chuck, From your pics here, the finish doesn't bother me unless someone comes along and suggests the coin was cleaned (and retoned). Still looks nice. Both of them do. :thumb: Hope this biased opinion helps you decide not to dip 'em. :smile

    Thanks for reassuring me to stay outta da kitchen! ha

    Besides, although I've got coins that I have stored for over 20 years, someday they won't be mine, and I don't want to destroy them for the lucky guy that gets them next. They won't be ours forever, and there are only so many of them. I reckon we should respect the hobby for the next generation!

    Well, and if the coins aren't progressing then they are fine. When coins are toned to the rainbow colors the toning hasn't progressed very far. Once you start to get the black toning is when the oxidation layer has gotten thick and can become damaging. If the coins are stored properly once they reach the early (and IMHO attractive) toning stage...then there is no reason to dip them.

    Thanks all for your opinions and suggestions..

    So I did go ahead and dip my 50 oz and 10 oz bard of silver to make it a little shiner and it looks great..

    I'm happy with it, more so than before..

    Does dipping silver cause any future issues with toning, tarnishing, etc? Or will it hold the shine for years to come with no discoloration?

    Did you rinse the bars in water (preferably distilled water) after the dip, and then patted it dry? There can be issues if the dip wasn't fully removed. The bar will begin to tone again, how long it takes, and how strong the toning, all depends on the storage/environmental factors. Also silver is probably more prone to toning after a dip.

    Actually, if rinsed correctly, it isn't. Bars, just like coins, have a luster. No, not like the luster on a coin, but a luster all the same. And once that luster is removed by dipping them, it takes longer for them to re-tone just like it does with coins. Assuming of course proper storage methods are followed that inhibit toning.

    After "Dipping", isn't the metal even more susceptable to the bad elements?

    I mean, isn't it even more likely to look bad sooner than before?

    Oops, I started this before I saw your post Doug. I guess your reply explained it.

    But what if the dip was done correctly, and the luster wasn't removed. Wouldn't it then be more susceptible to toning then? I've heard that a few times, and always believed it to be true, but I could be wrong.

    Some luster is always removed by the dipping process...it just depends on if it is noticeable. Luster is caused by the surface of the metal being irregular. Dipping removes layers of the metal from the surface making those irregularities smaller. If you over dip, too much of the surface gets removed...it gets too smooth and it looks dull.

    Yep, and in those cases of over-dipping, even when the coin retones the dipping is noticeable. And I agree with Doug, when a coin is luster is removed it becomes harder to tone. But, I'm wondering about when a dip is done correctly, when the thin layer of silver sulfide is removed, but the luster remains. I've always believed in those cases the silver would be more susceptible to toning.

    I wouldn't think so...the reason is is the layer of metal that creates the luster, that irregular layer, is less pronounced. This is the same layer that causes the toning to be visible...light refracts through it to those irregularities and basically creates a prism resulting in the colors. If those irregularities are less pronounced...then the toning will be less. It's the same reason why an over dipped coin tones slow only less extreme.

    No matter what, when a coin is dipped some of the luster is removed. And the less luster it has the longer it takes to tone. But of course that is if the dipped coin is compared to an undipped coin.

    Now, what you have probably read or are thinking of is something like this. Toning, in and of itself, puts a protective layer on the coin that slows down additional toning.

    So a dipped coin with some luster remaining will tone faster than a coin that is already toned. But it will tone slower than a undipped, untoned coin with full luster.

    You have to keep in mind that we are talking about 3 different animals here -

    1 - a fully lustrous and undipped/untoned coin

    2 - a previously dipped coin that has some luster remaining; but that luster has been smoothed out and lessened than it originally was by the acid in the dip

    3 - a toned coin

    So when I say that a dipped coin will tone slower than an undipped coin, what I am talking about is the same coin in two different states of condition.

    I am talking about the coin in its original condition as it came from the mint. Let's say, purely for the sake of illustrative purposes, that it took 10 years for that coin to become toned.

    Now that coin is dipped, removing all of the toning and part of its original luster.

    Now for that same coin to re-tone, back to the point it was immediately before it was dipped - will take 15 or 20 years, if stored under the same conditions it was originally, instead of the 10 years it took the first time. And the reason it takes longer is because some of the luster has been removed.

    I guess the main point is this - the more original luster a coin has, the faster it will tone. Lessen that luster and it will take more time.
