About this set: After assembling the Joshua collection of Mercury Dimes that was auctioned off by Heritage at their October 2000 Long Beach Sale, this collector decided to put together another set that would be the finest set of all time. Within 15 months the Joshua II collection was completed with a higher ranking than the famous Dominick collection. This set boasts all the key dates in the highest condition available - 1916-D MS67FB, 1918-D MS66FB, 1918-S MS67FB, 1919-D and 1919-S in MS66FB, 1920-S, 25-S in 67FB and the 1923-S in MS66FB. No coins grade below MS66FB. A total of 75 coins are the finest known. 30 coins are MS68FB or better and 36 of the coins are MS67FB. While the set is now the finest known it is not finished. The set now has an average grade of 67.26.
