Here are two coins that seems to stand out from my recent Romans and Byzantines.. The top one appears to show the bust of tyche but I really can't tell...any ways to get rid of the bronze disease? Should I soak them in distilled water? Chemistry was never my strength The other one in the bottom is sluggish beyond repair  but I can make out something that that seems to show some sort of a beast or a horse...Thoughts?  |

The bottom is a provincial of Augustus (maybe Tiberius). It shows a priest, or a colonist, or a founder, plowing right with oxen or bulls. Its on a tiny flan for the type.

I'm surprised someone managed to guess the bottom ! What do you mean by tiny flan? The coin is quite thick! Should I soak it in distiller water though?

Does soaking them in distiller water get rid of the bronze disease ?

Soaking in DW will not get rid of Bronze Disease. Also keep the coin away from any other coins, it can transfer. If you have kept the coin in a flip, you need to throw the flip away.
There are lots of methods for halting BD. You can search the forum, or google for more information. I use verdi-care, you can google that as well.
The first thing to do is to get rid of the green. If it is flakey or powdery it has to be removed and you have to be quite radical about it. Anything that is left behind will cause a regrowth.

Like a little plastic wallet for holding the coin.
DW does get rid of BD...but its a very long and drawn out process to do it. First, remove all of the green powder from the coin. Blitzkrieg it - go straight to metal, dont hold back on it. Its important to remove it all. Next, you need to soak the coin in DW - this ebbs out chloride ions, which are the cause of BD. Of course, you'll reach equillibrium in a couple of days. So you need to change the water regularly, or you'll start depositing chloride ions evenly over the coin which would not be good. Each time the water is changed, you must dry the coin and give it a rinse in fresh DW. If any green shows up, remove it. For a badly effects coin, this process may take months, but it is possible to save even badly afflicted coins.
The augustus should have legend around the bust and a neck, as well as a legend around the plough scene. This is struck on such a stumpy flan that none of it is visible. Maybe it was clipped?

Thanks for the info guys! Much appreciated! And by going blitzkrieg on it :P should I use a needle to pick them carefully pick me out before applying DW?

I believe your first coin is from Phoenicia with the turreted bust of Tyche, I can't really make out much of the reverse so I'm not able to pin down the exact coin.

It could be a palm tree but I'm not sure ... Anyways in trying to get rid of the BD like you said but is is it normal if the brown stuff is coming out as well? I stopped as soon as I saw it because I don't want know if that's the dirt or the patina

The top coin is down to bare metal. the brown is either caked dirt or another kind of (stable) oxide. Id avoid removing it if I were you, until you're a bit more experienced and know what you're up to.
