Barbarous imitation of augustus dupondius

Hello everyone! 

This dupondius I own has been very suspicious to me for a while now, the weight is incorrect (7,54 g), the metal is so low quality it looks like those logs eaten by worms you see outside sometimes and the SC, oh the SC is just awful. It looks like the handwriting of a toddler and for some reason has a comma between the two letters. So for these reasons I’ve decided to ask the forum, have you seen similar imitations of Augustus coins anywhere? Personally I haven’t seen these barbarous counterfeits anywhere earlier than Marcus Aurelius, so might this one have any added value for age reasons? Thanks in advance for any insights given!

Actually, I've seen one, when he was still Octavian:

RPC I, 620A: https://rpc.ashmus.ox.ac.uk/coins/1/620A

Imitiation of that dupondius DIVOS IVLIVS with the portraits of Octavian and Julius Caesar.

I own one of these, or not. It's worn to the point that it's hard to know if it's the original or barbarous. (it's very underweight, which may point to the latter)

I left the question in open, because it's still a coin with the portrait of the one and only Julius Caesar on it.
