1919 DDO Mercury
Going through my mercury dimes that I found with my metal dectctor over the last 45 years, I found a 1919 Philly. I see the new buzz about the DDO version with the doubled motto. What I cannot find, however, is one with all four digits of the date doubled instead of the motto. Is this a version that I should send somewhere for verification or are doubled date mercuries just all in the $20 range?
