In page Lincoln cent:

"

Brenner objected to the removal of his initials, but his protests were to no avail. The cents without Brenner's initials were in production by August 12, 1909.[9] During the halt, owners of vending and slot machines complained that the new pennies were too thick to fit in their machines.[10] Barber was recalled from his vacation in Cape May, New Jersey, to deal with the complaints. Leach ordered changes in the new cent, but Barber resisted Leach's orders, and was in the end successful—vending and slot machine manufacturers modified their machines to suit the new cent, rather than the other way around.[11] By the end of 1909, supply of the new cents was finally up to demand.[12]
