What is a floating roof

A Floating Roof can occur due to excessive grinding to the Reverse Die by a Mint employee in attempt to repair the Die or remove a Die Clash and they ground off the ends of the upper roof walls. It can also occur due to grease.


Normal Reverse


Reverse of O.P.'s Cent

It can also just be a weak strike and I lean this way due to the lack of steps and abnormal blending of the 'o' in the word 'of' at the top of the penny in addition to the lack of roof supports. A weak strike with a tad of wear can make many things disappear and I don't believe there's much value in this, but certainly more than a penny.

Is it only found on the 69-D coin! Interesting.

While a weak strike can cause the lack of details on coins but since the letters, Date and Lincoln's bust are all there on the Obverse of the O.P.'s 1969-D Cent, I doubt that that was the cause. It is more likely that grease, possibly excessive grinding and/or a severely deteriorated Die was the cause. Note: The indistinct details of not only the steps on the Memorial Building but also the shrubbery on both sides of the main steps and the missing Designer's (FG) initials (which I missed seeing previously).

No, there have been quite a few Lincoln Memorial Cents of different Dates and from the other Mints that have been found.

Not that it is the sole indicator, but I just sold a few of the floating roof cents in a collection on eBay. It ended about an hour ago and realized $182.50.

Not to pick a nit, but you don't need both sides to be weak to have a weak strike and you've just listed off some of the causes of a weak strike on one side. All good reasons.

This surprises me, but if someone is willing to pay that much for it then all the better for you.

As I said, it wasn't the sole item driving the bidding. I'm well aware of values and the collections I sell. Minimum they sell for $180. Often they are $200-$225. But no one can predict the max value as all it takes is 2 persons to want the same items. The most was $375 and in my opinion, it was no where near the value what the buyer paid. But I don't make the rules.

No nitpicking but in minting (striking) coins, you have an Anvil Die and a Hammer Die, the Planchet sits atop the Anvil Die and the Hammer Die strikes the coin exerting the same amount of pressure per square inch on the planchet whether it is the Reverse or Obverse. Therefore, the Obverse and Reverse should receive the same amount of pressure (weak, moderate or strong) during the striking unless something impedes that process, such as a piece of a broken Collar, mis-aligned Die, planchet not aligned in the Collar (laying partially outside the Collar), grease or other debris, damaged Die or other.

Huntsman, I think we agree and I wasn't accusing you of picking a nit, but I was just saying I wasn't picking a nit in what I had said.
