Message:: [QUOTE="Jaelus, post: 2947869, member: 46237"]This is an interesting question. The only set I have with 69s are proof restrikes, the oldest of which was struck in 1967 (PF69 UCAM). I did a quick search through my primary type set (Hungary 1848-1956), but I thought it would be interesting to look at this data by planchet composition: For Aluminum, there was no significant correlation between age and grade. At the date in the collection where aluminum appeared as a coining metal (1946), it was just as likely to be any grade in the MS65-67 range. The same went for Aluminum-Bronze. This is not surprising as these are both relatively modern and light coining metals, so bag marks would be limited. All copper-nickel fell within the MS65-67 range with the oldest MS67 from 1950. The oldest bronze and oldest nickel examples in the MS65+/66 grades were all in the 1890-1910 date range, which is when both bronze and nickel coins started appearing in the type set as well. No iron, steel, or zinc examples exceeded MS64. No copper examples exceeded MS65; the oldest was 1848 (the first year of the type set). Similarly, no gold examples exceeded MS65, with the oldest from 1887. I did not find silver graded MS66 before 1915, before 1892 for MS65+, or before 1868 for MS65, however, those grades were all represented heavily after those dates.[/QUOTE]
