Curious what people here's experience has been. For each denomination, how many significant variety (or error) finds would you say you have? Specifically interested in each of the following: Pennies: doubled dies on pre-single-squeeze era coins (I think about 1986)? Doubled dies you deem "significant" on any penny of any era? significant RPMs? Design varieties (close AM, WAM, reverse of 89, etc)? Cuds? Major errors? Nickels: Major DDOs? Major errors? Significant RPMs?Anything else? (I haven't hunted nickels much) Dimes: Doubled dies on pre-single-squeeze doubled die varieties? single-squeeze era doubled dies? Significant RPMs? Major errors? Quarters: pre-single-squeeze era doubled dies? single-squeeze era doubled dies on the center of the image? single-squeeze era doubled dies on the devices? Significant RPMs? Design varieties (e.g. RDV-008)? Significant errors? |

My guesses at my odds: Pennies (Odds per box): Pre-single squeeze DDs (Before 1997) - 1:1.5 "Significant" DDs (I'll go with CPG Listed) - 1:10 Significant RPMs - 1:5 WAM/CAM varieties - 1:10 Cuds - 1:30 Major Errors - 1:25 I've searched maybe two $100 boxes and a handful of rolls of nickels. No significant RPMs or errors, and no major DDs. A lot of single-squeeze DDs though. I've searched through a few dime rolls, I'd say ~$150. No RPMs or errors at all. One pre-single squeeze DD (1970 WDDR-005). Single-squeeze DDs come up around every 2 rolls. I think the odds are much better for quarters compared to nickels and dimes, although quarters are way ahead of dimes and nickels in the number I've searched. 5 pre-single squeeze DDs (4 are 1970-D DDRs, the other an extremely rare 1971-D DDR). Single squeeze DDs are about every 2 rolls. No RPMs, design varieties, or major errors. |

Awesome information, Tanman! I've only hunted a handful of boxes of pennies and about 2 boxes of quarters, so great getting this kind of data from people who have searched far more. How do you decide which varieties you do/don't actively search for? I've done most of my hunting since the start of covid, so I've been hunting extremely exhaustively, since it seems inconsiderate to ask the bank for more coins before I've thoroughly searched all the ones I have. Not sure what my cutoff will be once things are back to normal though.

I search for everything, as long as I know about it.

Title wasn't really the question, John, there's just limited character space. Obviously every box will have at least one (and probably dozens) of minor doubled columns in the center bay.

Good to know, Tanman! I think this will be how I do things, too. It's a little tedious spending a couple days per penny box, but I don't like the thought of missing a rare variety just because it wasn't on my list.

Also, Tanman, I noticed you use 1997 as the start of single squeeze hubbing, but I know CONECA insists it was in the mid 80s. I read this article ( https://conecaonline.org/so-just-wh...bbing-begin/ ) where they make the case for the ~1986 start date, but the author doesn't really explain where the 1997 start date comes from and kind of just presents it as a strawman version of the argument. Why do you go with 1997 rather than CONECA's date? |

That article says it was developed in 1986, but it doesn't say it was fully implemented in 1986. "(During FY86)... in pilot testing for production dies." Ken Potter assumes these test dies were put into production, which may or may not be true. There's no evidence, just an assumption. Both Dr. James Wiles and John Wexler say the US mint "began experimenting with" or "was in the process of developing" the single-squeeze method in 1986. In the Summer of 1996, the Denver Mint opened its own die shop with the single-squeeze presses. Before this, the Denver Mint was supplied dies by the Philadelphia Mint. Both Wiles and Wiles say the Philadelphia Mint "began" using the single-squeeze process in 1997. And due to issues hubbing the larger coins like the quarter and half dollar, it wasn't until 1999 that all dies were made using the single-squeeze process. http://www.varietyvista.com/Watershead%20Dates.htmhttp://www.doubleddie.com/58201.htmlIt is absolutely possible that some Philadelphia Mint production dies were made with the single squeeze process between 1986 and 1996, but it also 100% certain that the multiple squeeze process was still being used in that time. Therefore, it is not really practical to call 1986-1996 the single-squeeze era, as a majority of dies were likely still squeezed multiple times. 1995 FS-101 and other DDs from the time are good evidence for this. |

Cool! Thanks for the great information!. My best find so far is a 1996 DDO-001, so cool to know that it falls in the pre-single-squeeze era (which I find more interesting, personally)!
Edit: wow, I just pieced together why Variety Vista lists 1996 in two different categories (1959-1996 and 1996-2008). Can't believe it took me that long to put two and two together. Some of the coins for that year show single squeeze DDRs, while other show pre-single-squeeze doubling, is the reason, I assume?

Yes, 1996 DDO-001 was definitely a die made with the multiple-squeeze process, at least in my opinion.
