Even if this coin could be identified, it's too far gone to be of any numismatic interest. I suppose it could be some extremely rare coin which could make me possibly change that statement.
Even with better pictures I think this one is a goner. There's almost nothing even close to being ID-able in this coin. It looks like it's been put through a bench grinder and polished shiny. Ouch What's the gold-colored coin just below the bronze in question (inside the folder)?
You mean this? I agree. Someone tried to destroy this coin. The coin you are interested is hadrian denar Italia???
The mercury U.S. dime appears genuine. Unfortunately the Hadrian is not. I am not familiar enough with the rest to offer an opinion.
I'm almost certain Morocco, France, and Mexico are genuine. I don't know enough about the other countries, but Portugal also looks good to me. Litmus test for authenticity: how much did you pay? If you paid a couple hundred dollars for all this, then most likely. If you paid between $10 and $50 for everything, then most likely not. For example, France and Mexico are both in the $20-range. Remember: if a price is too good to be true, then it is probably not true.
That depends on whether or not they are silver. If most of them are base metal, then it's not unusual to pick up a lot of miscellaneous foreign coins for $10-$20. However, most of those coins appear to be in really nice condition, so I'm guessing they would cost a lot more.
Ok. I'm sorry guys. All of them are 100% checked silver coins. Story behind them deserves a book. Point is I didn't EDITED asked for it and about 280 other coins I bought from that guy. But it changes a EDITED lot. For just 80 euros LOL
I'm not sure about ancient coins that's why I ask. My hadrianus denarius might be fake Coin I know that 10% or more up to 20% may be fake and I don't EDITED care Point is that in this collection are coins that makes my jaw drop and until I'll be 100% sure you wont know haha. EDITED yeah Many people my position. Not numismatic. I w.knowledge but with some advices will agree I'm polish sorry for all grama I'm not fluent in English But I'm sure I'll bring you a edited lot of numi-PROBLEMS HAVE A NICE DAY
