Really? Most do not want to say what a coin may be worth and possibly offend the buyer. Some of us, me included, have no problem saying what I think. Do you really think we, on this forum, do not share our thoughts? Come on!
The more I see threads like this the less interest I have in answering. The fact that someone does not answer within a half hour of a question does not mean they are dodging the question. It could mean they do not live online and only see these posts a few times a day. Tonight is Shrove Tuesday or Mardi Gras (depending on how you party) so I was out. I have seen coins of this quality offered for everywhere from $30 to $300. I would not pay more than the $100. It is a nice coin but not one I am seeking or one I'd pay extra for just because it is high grade. I find it interesting that one of my more silvered FH coins is this Gallus from Cyzicus. I realize it is not as nice as yours but the fact that it also retained that much silver suggests that this mint may be one that did the silvering well. I recall thinking that this Gallus was worth the $15 being asked for it so I bought it even though it is not perfect and, that day, I did not know I was seeking a Gallus from Cyzicus. That is how I, a collector not a dealer, work. I did pay $131 for a silver-free and imperfect Trier that I needed to complete my mint set but would not be tempted to upgrade a $15-20 Cyzicus with a really nice one at $100. The Trier was a Bridgnorth Hoard coin which were (and still are) being offered for more than I generally would pay but sometimes we pay more and sometimes we pay less. It averages out in the end. If you want the coin for a reason other than what it is worth, you don't care if you pay a bit too much. If you care only how much you can sell your coins for, perhaps you are a dealer and not a collector. I'll take this to mean you don't want answers from members of the TLC in the future.
I did answer your question if you took the time to look. You asked what it is worth. It is worth what the buyer is prepared to pay for it. I would pay no more than £20 GBP, because thats what I can buy them for. You paid $100, because you liked it and were prepared to pay that. Others would pay nothing because they would not want it. Ken would not pay what you did for that coin, because he is a dealer. Doug is right, some wont comment, because they do not want to give a value lower than what you paid so as not to upset. Some wont comment, because they dont know and some wont comment because they do not have the time. Maybe if you had not said how much you paid, you would have received more replies, maybe not. For the record, I also think your comments to Doug were disrespectful.
Here are some examples of Roman coins that certainly show evidence os replating in more recent times. Having done some research on the subject it would appear that some Victorian collectors liked to resilver coins in their collections. Ho hum. These coins were bought in my early years of collecting ancients and it wasn't until I had handled many more coins that these stood out as having significantly different silvering characteristics to normal fully silvered coins. Both coins sit between my collection and my black cabinet. Both coins are ancient but have been tampered with.
