Hi I have 2 coins here for opinions on error and/or value, if applicable. The 2013 cent has a large (occluded?) gas bubble on obverse next to nose. I haven't seen one this large and find it odd for it to happen to such a degree on a newer coin. The 83p dime i'm near certain is environmental damage but as a new hunter/collector, wouldn't mind a little confirmation. Sorry for pic quality but that' s all i have for now, thanks!
if you roll search cents an start collecting zincolns with plating issues/bubbles your gonna have a huge collection!
