@higgin, first welcome to CCF. Second, it looks to me like this coin has ben damaged in two ways: first, someone tried to cut into it with wire cutters and second, someone drizzled solder on it. Depending on how old that solder is, it might very well contain at least some lead. Neither of those are mint errors though.
