That's an interesting atypical 1919. The obverse is very shallow (possibly due to a worn die, often seen on 1919H pennies) so giving a good rim on the reverse, and very well struck up head, face and chest of Britannia, which are more often weak than not.

Once you've done it once or twice, you get to know what info to cut 'n paste before you start.
If you get that one just right, by which I mean untouched for decades, you might be lucky to find it has a unique purplish patina that I've not seen on any other medal. I've seen several over the years and it's just the most beautiful colour. Probably a reaction to a particular alloy.
Looks the real deal to me. And those lines don't look to be scrapes from photos, but rather toning streaks. Don't think many of us would shoot you for a dip. Have to check the weight bit...
Addendum: weight is correct as well.
I would always take a genuinely toned coin over a lustered shiny one. It gives character and a life rather that a flat perfect disc.
I would leave it alone, it looks lovely
