Starting out 2018 bottom-feeding on eBay. Pretty happy with this one, a dupondius of Lucius Verus, Mars reverse (I'm still trying to attribute it - the TRP V on the reverse is stumping me). Just under $6. Anyway, as you can see, it has a small loop soldered on. Any tips for safely removing it? Can I heat it over the stove to loosen the solder without damaging the coin?
