I just stumbled across this one last night in a grab bag of 100 pennies from the LCS. actually there are 2 of them, both 1979. I have never seen a finish like this before so I am looking for some advise and opinions. I will also post some better pictures of both coins later when I have time. I have seen pictures of rippled coins before and read the threads on this site, but those ones seemed to be quite dull in appearance. this (these) penny must have been just cut out of a set because of the brilliant finish. or is this just simply a Struck Through Grease? I think I understand correctly that a rippled coin is from the first few strikes of a new die and the grease dissipates and quickly fades as more coins are struck. no matter what though, it's a good looking coin!!

i don't believe it is Struck Through Grease but I am not certain, it looks to be a proof or a specimen. very interesting though. maybe the copper was not a proper alloy.?

Very nice finds all good, I'd be pretty happy with that bag o' fun. Very thin film of grease I presume on those 79s definitely a premium there. A 1955 hanging 5 I've yet to see.

anyone else have thoughts on these 2 pennies? I examined a '79 uncirculated set and these pennies had definitely just been released from sets. I am putting them in their 2x2's and I want to label them properly so the more info the better!
a general valuation would also be appreciated :)

I would double-check to see if the coin has been coated with shellac -- that could alter the surface appearance. I've been fooled by shellac'd coins in the past, thinking it's an error coin of some sort. Dipping the coin in acetone would dissolve the coating (if there is one).

I know it hasn't been coated because the LCS where I bought the bag of pennies told me that they had just released a bunch of coins from sets including most of the mint state pennies in the bag. Plus that struck through thread on the one coin is incised and a post mint coating would have filled the incised area IMO. Good suggestion though! Thanks.

I'm wondering about the weight? Is it possible that the planchet was flawed? Impurities in the base metal? Nice finds

I checked the weight of both pennies and they are at 3.23gr and 3.26gr. Well within mint tolerance. I am guessing that they are struck through a thin film of grease (and a thread on one) as pennyman007 states.
Would a value of $20-$40 each be about right?
Thanks

Those are specimen singles, which came from the mint in 1979 with a lacquered surface in the double dollar Prestige Sets (Yes, the RCM lacquered the specimen cents in the 1970s, to preserve their lustre). You are seeing a disturbance in the lacquer, either from packaging the specimen strike too quickly, before the lacquer hardened, or post-mint with the lacquer either being exposed to heat (shrinking) or a solvent. Pick any 1979 specimen coin, and soak half of it it in a strong solvent... or hold one in a pair of pliers and take a paint stripping heat gun to it, or pull one out of a junk bin, and scrape the surface with a sharp needle... you'll see lacquer shavings with the latter, or really cool surface patterns with either of the former. As an impaired specimen, it is not worth much more than 25-cents.

Aha! Awesome...The man with an alternate answer and very likely the right one.
Roger...Would the coins be laquered if they came from an uncirculated set in the plastic wrap? (Which is what I was told after I found them and questioned the LCS)
AND are you 100% sure that it is lacquered? (Before I start testing it with solvents etc...)
Which testing method do you recommend? I will gladly post pictures and results. Lol.

You mean you have them in hand and didn't try scraping them with your fingernail or a toothpick?..oh well lol If they're only worth 25 cents as suggested by SPP then clean them with whatever but I'm sure your safe with acetone.

I did try to scrape with my nail but the surface was smooth and metallic feeling and my nail didn't do anything at all to it. I didn't want to damage the coin's condition so here we are! Lol. I didn't try a toothpick though so I will try that tonight.

The PL singles were selectively lacquered from 1961 to 1967, meaning, some were, and some were not - see my CN Journal article (Canadian Spice, June 2014). I don't think the PL singles in the 1970s were lacquered. The Double Dollar Prestige sets, after 1974 and before 1981 (when proof strikes were introduced) definitely were. Oddly enough, the double cent specimen sets (small red boxes, without the silver dollars) did not have lacquered 1-cent coins, and you find some nice toned cents in those sets.
If you want, I can sent you a specimen single from that same year, then you can "have at 'er" with solvents, tools, etc... - drop me a PM. I'll put a good scratch in it, so you don't feel compelled to "save it". The only caveat is that you photograph and share your results here. It is more like an epoxy than lacquer - I don't know about acetone, I used a stronger solvent under the fume hood at work. Don't mess with solvents, unless you know what you are doing. The paint stripping heat gun is fun though...
