To my as yet untrained eye, it would appear that Apache Chief Geronimo would be a very easily forged signature, as long as the aging issue could be addressed. I am considering purchasing a Geronimo, and would like to get your opinions on it. So if you don't mind, what do you think? Would you care to estimate a value? I saw one on eBay for $3800, but it doesn't look as yellowed as this one. Thanks.
