Thank you both for the warm welcome and detailed information.
I googled the 1872 Straits and come up with this (you were right, the closer look at the appears to be 1872):
Year 1872 1872H
Mintage - 5,770,000
Note only proof Small H below neck
V.Fine - 20
E.Fine - 110
Uncirculated - 470
Proof 7500 Rare
I needed to google meaning of the each column. How do you grade those coins, because we are not sure if those coins would fit at least to "Very fine".
