1924 Peace Dollar

Hitwise, I see very little going on and this Peace dollar could make MS-65(without the spots), the fields are very clean. However, the black spots are troubling and could be some type of corrosion which would significantly reduce the value. I do not think I would be able to make that determination from pictures though, you should examine those areas closely with a magnifier and see if they look like stains/toning spots or if it could be corrosion.

I'm going with MS64. Nice dollar!

Couple thoughts:

Peace dollars are, like Seated coinage, kinda mushy in the details especially on the obverse. In the grand scheme of things, this one is pretty strongly struck. Obverse lettering is prominent - there's nice delineation at the edges where a weakly-struck coin would be less sharp and show flattening on LIBERTY - and although the center of the obverse is kinda washed out by the lighting, the lower hair details look very strong.

Now, look at the reverse. See the few very bright spots in the feathers? This is a hint to me about the nature of the lighting, and the important takeaway is that a worn coin, in this lighting, would either show more such highlighted areas, or none at all. I'm believing that the highlighted spots are the only rubs on a Mint State coin, so I conclude that this one is Uncirculated.

KisNap chose to light this one from almost-vertical, which would mask some chatter in the fields. There would be color breaks, though, if not visible gouges, and there's darn little to be seen. The little vertical gouge at 3:00 near the end of the hair is the only really visible mark in the fields, and I see another vertical mark below the eye (in the second pic). On the reverse, there are three small gouges on the wing, only the center of which really strikes the eye, and possibly a hit on the end of the are in DOLLAR.

Purely on technical merit, not considering the spots yet, I believe this coin is MS65 all day. This is not a difficult grade for 1924-P, a point to take into consideration when thinking about how a TPG would grade it (and that's my practice when grading).

On to the spots. I'm not willing to draw specific conclusions due to the lighting, and there are so many differing causes/possibilities for such spots that one must prefer to have the coin in-hand before saying anything definitive. As biokemist said, the difference between carbon spotting and corrosion would not be visible here, while making a big difference in how a TPG would react to the coin. An acetone dip (using the strict safety procedures we've talked about here dozens of times) would be recommended for this one; it would help to identify the nature of the spots.

It will not affect the value at all since it does not interact with the metal. An organic solvent like acetone will only remove surface contaminants. Is it a 1927-S or is that just a spot under ONE? I would grade it EF-45 as long as there is a reasonable amount of luster still present. That one would probably benefit from an acetone bath as well, looks like it has quite a bit of circulation dirt.

If the lighting is identical between the two shots, I see the darker highlights on the wingtips and obverse hair to indicate wear, leading me to agree with biokemist's grade estimate.

Paint supply or hardware stores carry it, the smallest quantity you can find will probably be 1 quart cans though. It should be 99+% pure but always do an evaporation test to check purity- pour a little bit in a clear glass container and it should evaporate with no residue left on the glass.

Always exercise due diligence in its use, just search the forum and you will find all of the precautions to take. As long as you are careful, it is safe to use for you and your coins.

that 1924 looks really nice after the bath.

Nice Peace dollar!

I agree this coin is particularly well struck.

IMO, I, however, don't see this coin grading over MS62.
