My suggestion is stick to your day job, there is nothing in your photo to suggest that the coin you have posted is off center at all. If this coin and your 82-D are a display of the knowledge you have learned from you tube you have learned nothing but misinformation. I am not saying this to be mean or hurt your feelings, that is just the cold hard truth.

Honestly, not that bad. Not a crazy nice work of art but still better than the dead presidents we have on our coins.

If there is a large coin show near you that would be a good opportunity to show the coin to an expert or two. Sulivan Numismatics deals in mint errors and does most of the larger coin shows. I don't collect errors myself so that is the only reputable error dealer that I am familiar with, I also like @Fenntucky Mike idea to post it on the CONECA website for additional feedback.

My herd of Buffalo coins is small, but I did recently add a couple of new coins to the corral. The PCGS TV does the coin little justice as the coin is much brighter then it appears and that carbon spot while certainly there looks far more intrusive than when viewed in hand, at least by me as the new owner.

I'm not sure that would be a correct term as we don't know if these are in fact from a die that became damaged, a defective planchet, plating bubbles or just what actually caused this particular effect. If these marks were caused by the rotary dial of the Schuler press I would expect to see curved lines rather than straight lines as any contact to the dies would be as the dial turns to move the next planchet into place between the hammer and anvil dies and discard the previously struck coin into the exit tube. I don't think we are going to be able to come up with a definitive or conclusive answer from just the photos, an in hand examination by an error coin expert is likely needed.

They could indeed be some type of die scrapes, however, if I am not mistaken, the mint was using Schuler horizontal presses at the time this cent was struck. If memory serves, the mint began to convert to the horizontal press in the mid 1980's. That type of press does not have feeder fingers, it uses a rotary dial (similar to an old dial telephone for anyone that is old enough to remember one). So unless I have my dates off and this was not struck on a Schuler press, I do not think this could be called feeder finger damage.

Linear plating bubbles/lines. Super common no added value.

Sweet coins, wish I had a place for one or two.

Not cut off blocked off, most likely by a partial grease fill.

The effect on the op's coin can also be created from one of those sonic jewelry cleaner machines.

@KoyMihn you have found an exceptionally nice coin. The strike is nice and full as evidenced by the completely formed and raised (from the field) "O" of One on the rev. The luster is outstanding as evidenced by the outline that softly follows the obv bust, this is an indication of gem level luster on a Lincoln cent. That is the good news. The bad news is that the Denver mint production in the mid fifties was superb, unlike the Philly mint which has struggled with quality cent production since the mid to late forties. As such there is an ample supply of gem quality coins of this date which has resulted in a large population of MS67 or better 56-D coins as shown in the NGC population with 199 in MS67 or better and 110 graded by PCGS in MS67 or better. As noted by @Sandon this was a date that was heavily saved and even today there are many BU rolls of this and other similar dates due to the roll collecting craze. There is also what appears to be a possible stain or spot on the obv just under Liberty which could limit the grade. Unlike @Sandon this is a coin that if I had a group of coins to submit (I never advocate for submitting a single coin) and I was as enamored after an in hand review (very important distinction) I would very likely send this coin in to be graded as I feel it has a shot at MS67 from the photos.

I'll start the bid at $25.

A very valid explanation, all good.

@NheilCruising, if you read the text in the sellers last photo, it states (as you noted) that these are stock photos. They will send you this coin certified by NGC, but not necessarily that exact coin and certification number in the auction photos. Using stock photos is a common practice by many big sellers who sell hundreds (or more) of the same item, usually US mint products like this that are submitted for grading in large bulk lots. The different label may indeed have been caused be a reholder event, but it seems rather surprising given that there are collectors that actively seek the signed labels as shown in the NGC photo.

Not very much anyone can opine in lieu of photos or a TPG grade. Neither coin is difficult to find certified or raw, the 3cs can get pricey in AU and above for a nice eye appealing example. The 3cn is very common and inexpensive even well into the lower MS grades. I hope these work out well for you, but it sounds like you are paying high retail for what are common and possibly cleaned or damaged coins. Not trying to impugn the reputation of the seller but many a flea market seller has been known to crack problem coins out of TPG holders and attempt to sell as problem free, buyer beware.

Congrats Bill

Welcome to the forum, what lead you to phrase your question; "1966 US Liberty Quarter Dollar-Marriage?" in this way. In other words why would you be asking about a die marriage on a common coin with a production of millions of coins? As has been noted by the gents above both of these coins are very common and both in well circulated condition. The quarter is worth its face value, if you have a quantity (200 or more) of the Lincoln cents with the wheat back reverse, many dealers will pay 2 to 3 cents each for the value of the copper in each coin.
