Smaller coins came out better, with fewer remaining adjustment marks, because not as much force was needed to ensure that the metal flowed completely against the die surfaces during stirking. Gold coins came out better because gold is a softer metal than silver, so the striking force didn&#039;t need to be as strong to obliterate the file marks. Large silver coins such as silver dollars and half dollars didn&#039;t fare as well, and adjustment marks are often seen in the fields of early U.S. dollars and halves; occasionally, these file marks appear on the devices themselves.[/QUOTE]</p><p><br /></p>
