1943 D And 1943 Philadelphia Pennies

I have a client who possesses two 1943 pennies. One D one no mint. One weighs 3.1g one weighs 2.9g. they are not tooled down, or show any sign of tampering . He obtained these along with over a million other coins including 1909 VDB and about 40 cheerio gold dollars. My problem is there are so many apparently fakes that no one looks at these with any real knowledge,even the so called pro's don't give any merrit to them without even seeing them in person. I've never seen a fake penny. Kinda hard to create one when the mint has certain processes that cannot be faked, and if so then how can anyone say anything is real or not? I uploaded the obverse and can upload the reverse to anyone who wants to look at these and give me a intelligent opinion.
