Topps was experimenting with various foil-like products in the early 1960's and came up with 72 Embossed foil cards as a pack insert, one of two different bonuses that year. These are especially susceptible to wear and high grade examples are avidly sought after. There have been 322 Clemente's graded by PSA and this NM-MT 8 is only topped by four 9's, one with a qualifier. The obverse has nice corners and a surface that has a lot of relief on the Clemente portrait while the back has a classic Topps period look to it.
