Generally, for better grades, my take is:
1950's fairly scarce
1960's plentiful
1970's some denominations didn't get much love, so can be scarce
1980's generally scarce
1990's plentiful
2000's plentiful
1950's fairly scarce
1960's plentiful
1970's some denominations didn't get much love, so can be scarce
1980's generally scarce
