What type of error coin is most interesting/collectible to you? Why?

The 1995 doubled die Lincoln cent that I purchased in 2021 is of most interest to me. It is a beautiful high-grade example of the error and was purchased when coin shows resumed after all of the COVID shutdowns. This coin is one of my favorites because it is an error from my generation (I am decades too young to remember the ’55 double die), and it was acquired during a very enjoyable “freedom” trip after a lot of time spent at home without access to coin shows.

No error coins are of interest. I see no point in collecting mistakes.

My favorite error coins to collect were the Morgan and Peace dollars. I had roughly 20+ before I had to auction them off. They were hard to come by, but again, the hunt was part of the fun.

1919 Mercury dime DDO FS-101.

Not discovered until 2015, thus most are in lower grades due to circulation. Many have been remelted down over the years. NGC census show a total of 12 pieces certified, the PCGS census shows a total of 32 pieces and the CAC census shows 12 pieces certified as of today [May 4]. 56 certified pieces total.

Let us do a comparison, say, against the popular error of the 1916 Buffalo nickel DDO. NGC census 119, PCGS census 207, CAC census 48. 374 certified pieces total.

Or the 1916-D Mercury dime. NGC census 5,982, PCGS census 10,137, CAC census 1,017. 17,136 certified pieces in total.

While the current value of the popular 1916/16 Buffalo nickel has been widely published since the 19-teens in many publications, the 1919 DDO Mercury dime has remained and still remains out of the limelight. Many collectors and dealers don’t even know this obscure piece exists. The 2025 “Red Book” still has not even published this true rarity in its book.

Some information can be found online via YouTube, Coin Talk, Collectors Universe, etc.

The true rarity of this coin should and could exceed the value of the 1916-D Mercury dime.

I’ve been a collector since 1958, but it wasn’t until 2009 that error collecting grabbed me. The sheer numbers of doubled die obverse and reverse cents, in all four varieties issued that special Bicentennial year, held endless fascination for me and many of my numismatic friends. What I realized is that error collecting involves almost every skill needed by professional numismatists in analyzing and attributing coins. Searching rolls of 2009 cents, I amassed a decent collection of these errors, and I decided to write a book about my experiences and include my data from the many U.S. Mint “LP” boxes I purchased. My hope is that interest might be sparked among youngsters who can barely afford the “junk box” at local coin shows.

The 2009 doubled dies offer an inexpensive way to explore the hobby by searching U.S. Mint rolls known to contain these errors. Almost every 2009 error collector knows that the famous “Skeletal Finger” doubled die reverse (WDDR-006) is in the LP2 boxes dated 04/23/09, more concentrated in the morning time-stamped boxes. It is the same with other errors appearing in specific time and date combinations LP1 to LP4 U.S. Mint boxes. It has been 15 years, and I still actively search 2009 Lincoln cent rolls for errors.

I vote for the three-legged Buffalo nickel.

I started collecting in the mid-’50s when I was not even a teenager. The “Red Book” was my nightly reading before lights out, and I would daydream of finding a three-legged Buffalo in circulation. I never did, but I found a local antique store that had one for sale. I saved every nickel from my paper routes and hoped it would not be sold before I had the funds. Hooray, I bought it for about $10—my first error coin.

I like most error coins, but my favorite has to be coins struck on the wrong planchet. Especially pennies struck on dime planchets. I find it fascinating that this mistake could happen.

I am interested in VAM Morgans. Doubled dies are always a nice find.

I have a Mercury dime die clash.
