The 1941-D Walking Liberty half dollar is quite available in uncirculated and Gem condition. Starting in 1941, the Denver Mint Walkers were saved in significant quantities. I have seen hundreds of beautiful original rolls of 1941-Ds. The typical specimen is well struck with fantastic white frosty luster. The Denver Mints are somewhat scarcer than the Philadelphia Mints so they sell for a small premium over the Philadelphia Mint "common date" price.
