"A Study of World Mis-struck Coins"
"It seemed that there were some misconceptions about the relative scarcity of World misstruck coins. Phrases like "German (French, etc) error coins are very rare" or "obverse brockages outnumber reverse brockages ten to one" were heard, with no supporting data."
"A study was undertaken in 1989 to catalog known World mis-struck coins (excluding those of the U.S.). Goals of the study were to determine which types of mis-strikes were common or rare, by country and time period. The following data may prove useful to collectors, even though these 6000+ thousand coins are 'only the tip of the iceberg'."
