1960-D Lincoln Memorial Cent Large/Small Date - Which Would I Search?

Completely depends on the skill / eyes of the coin hunter who sorted and wrapped them.

Indeed, be very careful.

and good luck on your search

Best chance would be large date rolls.

Had to look up the production on these two types to see which was produced first.

It seems the 1960 Small date was produced first and then the dies were changed to large date. A few dies ended up with the "... small date hubbing over a large date hubbing".

Large date production followed small date production, soI would think they will be in large date rolls.
(Even if the dates on the variety look like small dates.)

Here's an interesting read in CoinWeek on the Small date & Large Date production hoopla.

I say this because the visible end coins in each roll will most likely be large date coins.
(With this being said, a lot depends on the sellers integrity whether the coins have been re-rolled as others have said.)

I do remember another forum where a member found many of these in multiple rolls. Needless to say, they bought all the rolls that were available. I reached out to see if they would share that information about what type of rolls they might be in but their messaging was full.
