Need help – not sure THX Ed “Extremely strong Class VI extra thickness shows on the date, LIBERTY, and IGWT. The strongest spread shows on the date and WE TRUST”. (John Wexler site) I am not sure of the date being extra thickness but everything else shows extra thickness. IMO Not sure but it looks like a die chip on the D of VDB. IMO Nothing on reverse that I see as far as markers.
