1952-D

Denver's 1952 output of 25,395,600 half dollars topped Philadelphia's figure that year and ranks among the higher production totals of the entire Franklin series. The D mintmark sits on the reverse just above the bell yoke, a placement consistent across all Denver issues from 1948 forward. Sinnock's obverse portrait of Franklin had been overseen to completion by Gilroy Roberts after Sinnock's death in May 1947, and by 1952 the working dies at Denver were producing consistent impressions of both the bust and the reverse Liberty Bell.

Mint State survivors are plentiful through MS65, and the 1952-D is widely available with Full Bell Lines (FBL), the designation grading services apply when the lower bell lines run unbroken across the bell's base. Compared with San Francisco product of the same year, Denver dies tended to fully transfer that lower bell detail more reliably, which keeps FBL premiums modest at MS64 and only meaningful at MS66 and above. Authenticators verify legitimacy by checking the 30.61 mm diameter, the 12.50 gram weight on 90 percent silver alloy, and the position of the D mintmark relative to the bell's upper yoke.

For the date collector this is one of the easier slots in any Mint State Franklin run, and registry chasers focus their attention on the FBL plus toning combination, where original mint bag examples with peripheral color can outpace technically higher grades that have been dipped. The condition curve flattens through MS66 FBL and then climbs sharply at MS67 FBL where supply thins. Eye appeal at higher Mint State grades typically depends on surface preservation and original toning patterns as much as on technical strike characteristics, with original-skin bag-stored examples commanding meaningful premiums over dipped or restored coins.
