It depends on how you define "Unsearched". All coins have obviously been looked at at one point... Many honest sellers have these listed, and you can get some nice hole fillers from those althouh, to be honest, i'd much rather suggest buying individual coins where you can inspect the quality of the strike and cherry pick the best coins
Prices differ on BU rolls by date and MM. Basically 40's and 50's rolls can be found cheaply enough but rolls of other dates in BU can get expensive. Rolls of UNC 1943 cents that havent rusted are also hard to come by (compared to normal coins).
Most people use Dansco albums for their
LWC collection, I know I have mine in one right now.
Most people collect by date + MM, as this is the standard. Usually the only error considered part of ones collection would be the 1922 No D. Some people choose to add the famous 1917
DDO, 1936
DDO, and 1955
DDO coins to their collection, and both the first coins can be found for under $150 in decent grade, but the 1955
DDO will set you back a few thousand.
Woody cents are amazing, although it is more often found on earlier dated coins in AU or MS condition.
Also, most people do not collect the proof coins as part of the
LWC set, as they dont have a special mint mark.
Some dates are prone to weak strikes, many early branch mint issues suffer from this. I've also noticed this on the early 30s coins as well, most likely due to the economic depression and the need for dies to be used for longer periods of time than usual.
Thats pretty much all that I can think of right now, if you have any other questions just ask. Also, I'm sure many other members will post on here as well.
SIDE NOTE: I suggest picking up a copy of Q. David Bowers' A Guide Book of Lincoln Cents (part of the
RedBook series hes writing) on
Amazon... It's only $15 and its an amzing tool!
