Look at these. Bank rolls, mint rolls, they all have these spots. I'm trying to put together a simple 2009 set of raw lincoln cents for my type set and they all seems to have these spots. I've tried xylene and acetone which can reduce them but not solve the ugly problem. Any ideas or is this just how it goes?
Hmm mine are in shrink wrap rolls the enders are good I hope the orthers are not showing spots like yours.
They look very much like "sneeze" coins. At this point there's nothing you can do if you want them truly original uncirculated. If you use something to remove the spots you're likely to find pits underneath.
Trying to prevent spots developing on rolls of Lincolns is older than I am. Point being, it's not just the zincolns that do it - and never has been. It is the nature of copper that does it. That, and our atmosphere. Lincoln cents stored in rolls developing spots and or unsightly toning is beyond common - it is the norm. And if your coins don't or haven't, then you're just lucky. So how does one do this ? Well if you've got any sense you'll forget about buying rolls, or saving rolls, and just buy individual coins that suit you. And yeah, there's a thousand tricks you can try, but most of them don't work. And not a one of them works all the time. Like I said, collectors have been trying since before I was born - with very little success.
The whole 2009 series is plagued with spots. My observation is the grading services basically graded them on the number of spots more than any other criteria. It appears these rolls were improperly stored which exacerbated the spots. The spots cannot be removed without damaging the surfaces.
Thanks for the info GDJMSP. I was looking forward to searching rolls for a few gems just for my collection. Oh well, off to eBay or the next coin show to find something decent.
I have a roll of 2009 Lincoln cents, chilling in the bottom of an old United States Mint bag. so far I'm getting a bit of dark orange toning around the rims.
Unfortunately it appears I'll have to go slabbed. Fortunately they are affordable, but it takes the fun out of the hunt. Of course all the other billions minted have these spots making the clean ones very rare. Snatch them up my friends!
Yes modern grading can be a real head scratcher. Looks like you curated a really nice set of 2009 lincolns though.
yea zzinclons tend to corrode easie , sad though our coinage has went from some great cawdy thing to a tiny coat of copper
In most cases, it's the pure copper that is the problem, not what's underneath. And even the 95% copper has always been a problem.
The spotting was so bad in 2009, they ignored hits and graded mostly on lack of spots. Pretty much all 2009 coins have 67 luster.
It's been difficult for me to find spotless raw Lincolns from 2009. Either they're sold in sets/bulk and have tons of spots, or they're graded and still need to be inspected for spotting. Doable but takes longer. I'd hoped to CRH.
I have both sets, the Bronze proofs are nice compared to the spotted circulation coins. Special 2009 cents struck for sale in sets to collectors had the metallic copper content of cents minted in 1909 (95% copper, 5% tin and zinc). Those struck for circulation retained the normal composition of a zinc core coated with copper.
