Everyone on this forum has collecting goals for their Lincoln cents. Some are attempting top 100 lists, some the CONECA library, others every possible listable variety. I myself would like a complete set of every CONECA, Coppercoins, and Wexler variety listed (minus the impossible 1958 DDO-001 of course). As a 26 year old I feel this is a good life long goal. In order to complete this, it is essential to have cross-references between the three systems. As many likely have previously, I have noted cross-references for myself over the past few years as I have spotted them. Subsequently, I decided to make a list to keep track of both the coins I have and the coins I need. This led to the creation of two lists, a 1909-1958, and 1959-date list. These lists are 81 pages and 63 pages respectively. There is around 7500 lines of coins between the two, each corresponding to a known variety, whether or not I personally have that coin yet. It does not list many 1991 to date varieties unless I happen to have those coins. It will likely grow to surpass the 1909-1958 list if I do ever get the modern varieties listed.

More recently, with the addition of the CONECA listings online for free, I decided to attempt a massive cross-reference of RPMs, DDOs, and DDRs from 1909-2008 between the three systems. I have been having some real fun doing this project, but could use a little help from the members here. As I have recently reached 100 cross references that could be listed by coppercoins, I have a couple that I think might be but really am just unsure of. A couple looking back are likely not correct. If anyone could help confirm or deny the cross-reference it would be greatly appreciated. This way when I send Bob a list it will be accurate.

Also, in spite of the randomness of the below years, I have been marking off completed years so I know which years to still cross-reference.
