..Lucius Verus...

Verus was my first thought too, but Aurelius is also possible. The Tium portraits of Aurelius are very variable and some look like Lucius Verus., e.g.:

https://www.acsearch.info/search.html?id=7680052

Unfortunately, the only suitable example for Aurelius  (RPC IV.1, 9534) is too big and too heavy.

Another similar example. Here the object looks like a branch (or the half of a lightning bolt) ?????

Probably two slightly different depictions of the same object

One note. Often the distilled water is not distilled but deionized, which means that the metal ions are replaced by H+. In this case the "deionized" water is slightly acidic. So take care that your water is distilled and not deionized.

I don't know about these coins, but there are some experts in artificial patinas. One guy brought in tonnes of coins with orange patinas on the market. Many collectors like the contrast, especially with black coins.

I know a collector who regularly steals his wife's "Foundation", a product of a well-known French cosmetics company, to apply it to his own coins.

If you hold the coin in your hand, you can easily tell whether the sand patina is real or fake. The real sand patina is less homogeneous, brittle and usually comes off in flakes.
