There's four RPM(s) running west and it look like RPM-004, to me . Here's the link to Coneca http://varietyvista.com/02b LC RPMs Vol 2/1969SRPM004.htm
Here's some listing on RPM from coneca for the 69-S http://varietyvista.com/02b LC RPMs Vol 2/RPMs 1969S.htm
The one I have could also be this one . http://www.coppercoins.com/lincoln/diestate.php?date=1969&die_id=1969s1mm005&die_state=mds
There are a few concerns I have comparing this coin. I would actually have to see another picture. Although its a nice coin I would focus on capturing over detail. --which coin is actually the coin , the big coin. We are going to find it today.
Check this out! I haven't touched this image besides downloadING it to my device..... I downloaded this image off of pcgs top 100 coins. Is it me or does it look like someone has gone in and edited the "196" from "1969"???????? There seems to be a blue dotted line going from the 1 to the end of 6. It extends up almost to the top of the 6 and it extends down to almost to the bottom of the 6. Cutting half of the first nine in 1969.
