A number of "Arnie's Army" replica badges from the 1960s were already listed on online retailer eBay, with one seller seeking $120 (96 pounds).
Palmer, who died in September at the age of 87, had a go-for-broke style that added to his appeal among his loyal fans, who became known as "Arnie's Army".
The white replica pins read "I am a member of Arnie's Army" in green writing with the Masters logo in the middle and the start date of the tournament at the bottom.
