That would make a bit better than AG-3 details, rather closer to full AG value, as it is G-4 details with a scratch. For context, half of Greysheet for G-4 is $215, while half of AG-3 is $145, so $70 in your favor. Technically, since the value is so high, it is a very rare piece even before the mintage figures. The demand of the 1895-O outweighs any mintage number - another plus on your side. Supply and demand will always be more important than mintage.
