Fishtank, Page 2
Beginning scan on top, after 23 hours below.
After a total of 4 days and two toothbrushings, we have 57.5 grams. I'm going to pull a couple of the coins and finish them. Sadly, about half seem to have encrustations. The small Byzantine (Half Follis? K)  lost almost all of the bright green stuff it had... not sure if it was an encrustation, beginnings of BD or a soft patina. Anyways, I like the looks of it now better. The larger rectangular coin (bottom row, 3rd from left in the above scan) has patchy patina. Some of the places that dirt was removed is showing metal, and looking at it more closely, the patina looks flaky. The larger coin in the middle row (next to the Byzantine in the above scan) has a densely compact clay on it. Looking at the edge and the clearer patch of the obverse, I'm not so sure of its patina either. Other than encrustation, perhaps 5 of these have been pretty much cleaned of dirt.
These 6 coins are going to go back into the fishtank, but I fear that there is more encrustation than dirt on them. I hit a couple with a silver brush/radial disk combo to better see what there was. 26.1g (9/17)

Here's the 3 I count as down. I am scared of losing metal from the large Greek Eagle, so pulled it, even though there is some dirt left on the one side. It doesn't have a patina, and the metal surface itself is flaking. The provincial (green) has dirt that when scraped off, just doesn't seem to lessen... so I threw it back in. The other two coins, I threw into Wurth's to see what it would do to the encrustation.
