I ordered a mint bag of the NIFC clad S mintmark El Yunque quarters. Planned to save the best and release some to the wild. None came out spectacular probably not one could be graded higher than a 65. Many were really disappointing with scratches and dints and unknown splotchiness. Based on what I got, I will be looking to buy one or two high graded ones as early as I can. This, if my purchase is representative, may indicate that the higher grades are infrequent and MS62 to 64 very common.
