The 1969 has no initials on the back. 1948 D wheat penny. 2009 different design on back. Are they worth anything? I am a total noob lol!
Welcome to CoinTalk...they are worth whatever they are worth to you. Nothing there that I know of that has much value. Other comment will follow, don't be too sensitive if they are jocular.
With the 69, I assume you're referring to the D variety with "missing initials"? If so, a large percentage of coins from said date and mint display weak/partial initials, and only those without nary a trace may bring a premium.
I agree that you can see the initials and the 2009 had 4 different reverse designs, all new to the older memorials. After this year the reverse design to date is the shield. Keep hunting for those lincoln cents!
