The thickness is very non-uniform from one side of the coins to the other. They're all 1999 coins and seem to have the thinner edge near Lady Liberty's feet for the most part. Sigma Metalytics shows them as being left to far-left (but still within the brackets). I don't have a scale or calipers but they diameter seems to be roughly in spec based on the little ruler on the Sigma. They do feel dense enough and the clink when stacking them sounds similar to my non-warped AGE's (although I'm definitely no expert). Any ideas if these are just US Mint errors/sloppiness (ie. misaligned dies or off-center strike)? I'm concerned about keeping them and losing premium/value due to the misshapen quality or having a potential buyer later questioning their authenticity. I understand that many coins can have some minor imperfections/inconsistencies but these are fairly drastic - moreso in person when looking at them than in the photos below. Sorry for poor photo quality - best I could do with my phone camera and my dad's camera doesn't have a macro lens. Thanks for any help. https://imgur.com/gW0qAEp https://imgur.com/543KrPf https://imgur.com/jZkC24h https://imgur.com/HXOITJu
