What makes you think that? The coin you have shown is not a mule, as Bob said it is simply a Sac dollar that was milled and the quarter inserted. Maybe an attempt at a magicians coin, maybe done to deceive, that cannot be known for sure. But what is 100% true is that you do not have an error or mule coin.

Yep second coin post tonight with rolling machinery damage.

Lem is correct, just damaged from coin rolling machinery.

No discrimination in this thread, if it is copper you can post it even if minted yesterday. Lots of die polish on the 64.

Agree that your coin is dated 1990, the lower leg of the second nine has been obliviated from some type of damage. Your grandfather may have found it interesting and that is why he kept it, but it has no numismatic value beyond the face value of 5 cents.

Thank you, those are much better, but alas as greenstang wrote these new photos prove that the coin has indeed been plated in the past.

Did you check Variety Vista to see if your coin matches any known DDO's for this date/mm?

Welcome to the forum, sadly your photos are woefully inadequate for anyone to give you an in depth evaluation. But what I can see from them and using your description, is a coin that has been plated in the past as a novelty item. That takes all the numismatic value out of the equation and leaves you with a value of approximately 3 cents for the copper metal in the coin. There is no way to opine on values you have seen online without knowing what and where you have been getting your valuations. However, it is not uncommon on sites like etsy, ebay, FB and others to have sellers that post outlandish prices for common and even damaged coins. Some are pure scammers out to land a big fish, some are just completely clueless and do not attempt to actually find out what they have or what it is really worth. As already noted above the 1930 cent produced in Philidelphia is common and does not command a high value unless in exceptional condition. This surprises many non collectors as many equate something that is nearly 100 years old as being valuable. In numismatics the age of a coin is only one part of valuation, condition of the coin, rarity of the date, and survivability of the date all play a part in how valuable any coin is. I will leave you with this screen shot of a 1930 cent that was graded by PCGS (in case you don't know PCGS is another firm like NGC) that sold for just $55. That may seem like alot for a single coin but consider that the grade of MS65 is a high grade, and it would cost close to $50 to send a single coin in to be certified and graded by NGC.

There is a pinned post in this section titled "coin marketplace guidelines" reading that post and following the guidelines would be a good start. My advice is to take your "Alot" to a local dealer to sell, most will pay around 3 cents for common circulated wheat cents (cents not pennys this is not the UK).

Plated, mercury plating was done often in schools for chemistry class. Nickel plating is another possibility as the guys that work in chrome plating shops love to have some fun and nickel has a weak attraction for a magnet. As Neo suggested whatever was used to plate the coin has begun to wear off over time.

Does not look like a DDO to me, plating blister or die damage is more likely. Bob's advice to post on the CONECA forum is good advice, if they think you have something they may request you send in for an in hand review.

PMD.

Paint, crud, who knows what is on that coin, but what is for sure it is not an error.

Welcome to the forum, as @Sandon correctly explained a doubled die coin is not an error but rather a variety. It may seem like we are hammering you on this point but it would be important because if you actually had a doubled die coin and submitted it to NGC as an error you would be charged the fee and would not get what you expected when the coin returns. Getting the terminology correct could save you money in the future. As already noted your coin is suffering from one of the worthless and common types of mechanical doubling vs true hub doubling. While these worthless types of doubling can be interesting to view, because they occur so frequently during the high-speed manufacturing of coins they have no numismatic value and TPG's like NGC do not attribute mechanical doubling.

Hello and welcome to the forum.

An abused entry in my 7070 set.

Your coin is not one of the so called SMS coins, just a normal brilliant proof.

Welcome to the forum, looks like a dryer coin. Coins get stuck against the drum of a clothes dryer and that can cause what you see here. Other possible causes are intentional damage to the rev and the rim may have been spooned. You can google spooned coins for an in-depth explanation and some comparison photos. But my money is on a dryer coin.

1922 Peace dollars are very common, circulated coins with the kind of heavy distracting marks and damage as your coin has sell for $20 to $25 dollars.

You seem rather confused on registry points, and it is registry not register, (this is not a place to shop for wedding gifts). Can you provide a link to where you found the point totals you claim here? In the future it might be a good idea to know what points a coin is worth for the set you intend to use it for before you buy said coin.

No.

Better, but still not in sharp focus, that is not a knock as coin photography is not easy. But I still do not see any significant die doubling, it for sure is not DDO-1 or DDO-2 as both of those have large spreads that would be very easy to see.
