Yes, if you haven't already removed to green powder manually, do so immediately. Then continue soaking the coin in fresh batches of distilled...
It looks like it could be genuine, but there is no way I would buy it from just the photo alone. I'd want to see it in hand first.
True, but I think we are seeing preservation (and subsequent cleaning) problems rather than original manufacturing.
By the time to OP was minted, the silver content was very low. Being buried in acidic soil could lead to the pitting shown on the reverse....
Grossly over-simplified, smoothing removes junky metal and corroded encrustations from the fields or flat areas to reduce surface roughness....
There are many provincial coins with comets on them. With little persistence you should be able to track one down for a reasonable price.
Keep a close eye on the one in the middle of the bottom row. If a bluish-green powder develops over the next couple of months, it would signify...
I am not bidding on this coin, so it doesn't affect me, but in general it is considered best to wait until after an auction has ended before you...
I'm not an expert, so take what I'm about to write with a grain of salt, (whatever that means). Generally, to spot tooled coins, you look for...
I live in Westchester County. I can't think of anyone who would like to search for coins with a metal detector, but I'm sure many people here...
That's not a bad idea. Of course, the metal detector would probably cost more than the coin is worth. I'd need to come up with something else to...
I'm actually conducting this experiment right now. Last summer I was photographing some coins on my front porch when I dropped one of them (a...
Well, there has to be something behind the coin. White, black, it doesn't matter. You have to make some decision, and whatever is behind the coin...
I think that's highly unlikely. It would take much longer for normal wear and tear to remove the patination from the high points of a coin like...
I started out collecting ancients by buying small lots of uncleaned coins--mostly LRBs, lots of slugs. I found that if I used a green 3M scouring...
The first shot was taken outdoors; thus, the higher shadows. The next step is to take some outdoor shots with the cloth background. It was too...
Hmm. Interesting that he appears to be an ancients dealer. Perhaps my assumptions about your coin are not accurate.
There is no obvious reason to suspect the authenticity of your coins from these photos. The dark color is just the result of the high level of...
Plated coins are called fourees. There were usually contemporaneous counterfeits. I don't think your Gordian III coin is a fouree. I think it's an...
Okay, I'll admit it. I just went and searched for "bronze constantine" since I have a fairly good idea of what many of his coins are worth. APMEX...
