Ancient Chinese coins

Hello, I couldn't find the exact match for these two coins, so I was wandering if they're even genuine?

Hi, 

For me look fine and genuine but you don't expect big money for it , maybe 10 bucks or less.

Cheers 

I just can't find the exact match for them on Numista or any other website 

Hello

this one seems genuine 

N#45905

the other one is  more an evocation of a Ban liang for me

The other coin is not Ban Liang coin, it is Liang Liang coin. But because those Liang Liang coins are very rare, I don't think this one is authentic coin. That type of authentic Liang Liang coins are funerary coins cast by Emperor WenDi ca 175-157 BC.

Is there any way of proving the autheticity of that coin?
