The 1929 Penny has the Indian Obverse die which is considered to be scarce. But there are alot of them around especially in the condition yours is in.
Yeah,lots of conflicting Info. on the 1929 Indian,i read on the net. a few years ago where only 1 die was used and the estimated mintage was less than 10,000 but having trouble finding link,found a similar one here..http://www.catawiki.com/catalog/coi...dian-reverse
Whatever the truth they're more common than the 27 Indian.
