found those 2 penny about 10 years ago in same roll , one can see the date 200x and other one too weak to see anything .what you guys think ?
Both of these cents are grease strikes. The strong design rim is unmistakable evidence of this. By the way, the term "die adjustment strike" should never be used to describe a weak strike. In the case of a simple, centered weak strike there is no way to determine proximate or ultimate cause. The idea that these are escapees from test runs is highly unlikely. Multi-error weak strikes (and weak strikes are associated with nearly every other category of striking error) indicate that these errors are the result of spontaneous and often short-lived press malfunctions.
The first Cent 20XX is a Struck Through Grease. The 2nd Cent might be a Die Adjustment but I'm not 100% sure.
I have a Struck Thru if you want to see an example - missing the same letters as yours but mine has the date.
I think you may have something there Kevin. Pretty cool coin, may just be what you think it is.. a die ajustment strike.

I'm not too well versed in errors, so this is very good info! I stand corrected. It makes sense that a true low pressure strike would not have strong rims.. I simply didn't think of that. Great info Mike.
