Does the toning make this worth more? I certainly love the tone! Especially on the reverse. How much could this go for?
Coins are only worth what someone is willing to pay for them. That's why if a coin has attractive toning there will be certain collectors who would like to display that coin in their collection and they might pay more if they really desire that piece. However, that coin is a really modern coin and the toning is too strong so it most likely is artificial toning. In which case it's worth very little. You can tell because the toning isn't even and instead it's really splotchy but that's just my opinion.
The coin looks slightly corroded, not toned. It was likely found on the ground and corroded while there.
i agree with the guys it is environmental or was in some other way created in an unnatural way;so it would not be considered to be a toned coin imo.
