Ron Guth:
The 1888 Half Dollar has the largest mintage of any of the Half Dollars of the 1880's, but 12,001 coins is admittedly a very small quantity by any measure. Even the vaunted 1878-S Half Dollars has a mintage of 12,000 coins and it is worth tens of thousands of dollars even in the lowest grades. Because of the small mintage, most 1888 Half Dollars are either Prooflike and/or highly reflective, and they are often confused with Proofs. Hundreds of certified Mint State examples exist, with dozens available in each of the grades from MS62 to MS66. Superb 1888 Half Dollars are true condition-rarities.
