Except for the big scratch behind Lincoln's head, that's a nice obverse on a 1970 S cent. What does the reverse look like? I suspect you're wondering about doubling, aren't you? The only thing I see going on is in the BER in Liberty. There's a lil' sumpin',sumpin' goin' on there, but I won't swear that it's doubling. We need a member with heavier experience to weigh in on this. Thanks for posting and Welcome to Coin Talk.
I did not know there are 23 different one for this date. The "ST" in trust look quite odd.Have you compared with these? http://www.varietyvista.com/01b LC Doubled Dies Vol 2/DDO 1970-S.htm
It needs better lighting. Looks like a single light source was used. Do you have a second to help reduce glare?
Wow, looking at and trying to figure out that stuff at this time of the morning(I've been up all night) is giving me a headache, BUT yes there may very well be something with that BER in Liberty. I followed alurid's link and the BER is listed. I didn't look for the ST. The question is....is you is or is you ain't....the real deal.
