Much better images would help greatly. However, it doesn't have the color of gold that I would expect.
I think you get the first post for free because I never see anyone with less than 2 posts. Peter should file a bug report.
Sorry, but no such thing as an Austrian 3/4 ducat minted in 1752. What you have there is a counterfeit 1 ducat of 1752.
