What is the most collected coin in the world? Well, that would be
the Abraham Lincoln One Cent. This site is about the Lincoln Penny.

The 1988-D Penny with Reverse of 1989 Transitional Design Variety
Lincoln pennies minted in 1989 have a modified reverse design with a New Font Style for the Designer Initials FG for Frank Gasparro. For reasons unknown, some of the last 1988 pennies made have the small but unmistakable New Font Style on them as well. This discovery was only made some 20 years later making Mint condition coins very rare and the Denver minted ones are scarce and hard to find in any condition. These are listed by Fivas and Stanton as 1988 D FS-901 and 1988 FS-901 Transitional Design Variety and are in the Cherrypickers' Guide Sixth Edition and soon to be in The Official Red Book hopefully.

Here is the Obverse side or front of a 1988-D Reverse of 1989 Lincoln Penny Transitional Design Variety RDV-006 FS-901.

Here are the Designer Initials on the Reverse of a 1988-D Lincoln Penny with the New Font Style meant for coinage in 1989.

Here are the Designer Initials for normal 1988-D Reverses. Most of the 1988-D One Cent Reverses have Poor Die Quality or Sharpness.
During the early part of 1989 I was searching through penny rolls putting aside the copper ones. I also went through some rolls with new pennies in them as well. Any choice brilliant uncirculated mirror like or choice strikes in early die state per say, I would staple them in 2x2 holders. One thing I noticed back then was that there weren't many 1988-D cents with high quality reverse dies with alot of details. However I did have a couple dozen or so of the 1988-D's stapled in the 2x2. Some 20 years later I learned that some of the 1988 pennies had the new reverse design intended for 1989. I dug out my box of coins and well it turned out that there were four of the 1988-D RDV-006 pennies. Due to the poor die state of the reverses of the 1988-D pennies, I think they used up all of the old reverse dies laying around, and in order to make quota for the year, they put in a few of the 1989 reverse dies. I think these coins are going to turn out to be pretty rare, espesially as people get wind of the variety. Best way to tell the difference is to keep a 1989 handy to compare with until you get an eye for it.

Repunched Mint Marks (RPMs)
Mint marks were hand punched into the working dies from the years 1838 to 1989. They used wooden mallets on tiny little punches. It usually always took more than one tap on the punch to get it right. Sometimes they would be mis-aligned making double, triple and even quadruple mint mark impressions. Sometimes the punch would bounce as well leaving double marks. Collecting RPMs is increasing in popularity especially as Canada is no longer minting pennies and probably the U.S.A. soon to follow. With the new technology such as Microscope Cameras and Pocket Magnifiers, finding RPMs is getting easier and easier. Here are a few examples of RPMs.

Here is a 1960-D/D Double D RPM-001. This is the most sought after RPM due to its clarity.

Here is a 1957-D/D/D Triple D RPM-016. There are impressions on the top and bottom.

Here is a 1952-D/D/D/D Quadruple D RPM-008. Three strong impressions and a weak one at the top.
