That's true...the term is 'doubled die' - not 'double die'.
I have looked through close to $20,000 in Lincoln cents since I started back in 1980. I have found thousands of die varieties in my years, but have found only three 1998
Wide AM cents, and found a couple of rolls of 2000 wide AMs. Problem is, I lived in the Denver mint district where no-mintmark Lincoln cents come only one or two to a roll. That was nice back in the day that RPMs were more plentiful, but since 1989 is the last date for RPMs, those have basically dried up as well.
Over the past ten years or so, the most common 'finds' in my searches have been the column doubled die reverse cents - collectible - nice - examples have been one or two per $5 searched in pocket change.
I have been far more into searching through "unsearched" wheat cents over the past ten years. I have been through ten times the number of wheat cents as memorial cents, and have a nice pile to show for it. Doubled dies, repunched mintmarks, the like. Usually two or three per roll, and I have found a number of quite decent doubled dies AND repunched mintmarks in supposedly unsearched (yet we know they were searched) bags and rolls. Thing is, most people who search them are only looking for key date and higher grade coins - they very often don't have a clue how to find what I search for...so every bag is unsearched to me.
I could bore you to tears with a list of my most recent finds, but that would be pointless. Suffice to say that they are still out there in great numbers, and are ripe for the searching by anyone who has some patience and is willing to search everything to find anything. Don't be tied down by lists of "dates to look for" and by books like the
CherryPickers' Guide. That's a great book to identify what you HAVE found...not to limit yourself to what you COULD find.
