Check with PSA/DNA or Global Authentication Inc.  These two companies are the authority for checking authenticity of sports memorabilia.

I guess that as with most things, you would need to take into consideration the supply and demand factor.  If you can find someone that really wants it, the higher price you will get.\nI would go to a pawn shop in the area if it something you need to do right away.  Bottomline is that you will get far more if you take your time and try to authenticate it and then locate a collector that is willing to pay a good price.  Maybe search some civil war reinactors groups around that area.

On Ebay, people are asking $200-400 for similar items (SB signed balls, bats, jerseys) but I don't see anyone getting them, a signed ball from 1998 only went for $12.50. I would say your cap would be worth $100-150 if he actually wore it in the game, less if it is just a cap you had him sign for you.

i would go to your local sports memorbilia store and see if they can compare it to a real signed ball or next time just dont buy it from a questionable place

Yes.  there are a few provisions.  You may autograph and have the item up for auction as long as there is NO FORM OF PAYMENT or FAVOR that is returned for the auction.  Think of it as more of a donation than an auction.  You or your teammates cannot recieve anything in return.

Take it to a sports and memorabilia appraiser.  If there's an auction house near you, they should have one.

First of all are these actual autographs or printed autographs?  If they are printed their value is of course a lot less.   Autographs in general of someone as important to the game of golf as Jack Nicklaus go for anywhere from 9.99 up into the thousands of dollars depending on what the item is.   One of a kind items being worth more.  With all 4 signatures on an item such as this (43 of 100)  could possibly fetch at least 40 dollars and possibly into the hundreds depending on condition and method of selling.  If you are interested in selling this item to the highest bidder on eBay and would like some help listing it, I would be happy to help you accomplish it for a nominal %.   Email me.

I imagine it would be worth a decent amount of money, but unfortunately Hank Aaron has signed an incredible amount of photos, cards, etc, so his John Hancock is easily obtainable.  The age of the photo will add to the value, but as you mentioned yourself, it's #22 out of 715, for that issue alone.  I would guess it's worth somewhere between $100 and $1,000 but you could always take it to be appraised.  \n     Ultimately though, a photo is only worth what people are willing to pay for it, so you might see if anyone else is selling Hank Aaron signed memorabilia on E-Bay, and see what it brings in.  \n     Also, if Barry Bonds breaks Hank Aaron's career HR record (which I pray every day that he won't, the cheater), that will drive the price down.\n     Hopefully this has been somewhat useful, sorry I couldn't give you a more specific dollar amount.

I would definitely try Ebay. I was able to sell some football memorabilia real easy, and I got a good price for it. There really is no one better than Ebay.

One side of the baseball has the commissioner of baseball's imprinted signature.  A. Bartlett Giomatti was the comissioner of the National League from 1986- April 1989.  I was probably in that time period

You're best bet would probably be eBay. There you can get so much sports memorabilia, and for low prices if you play it just right.

You can set up and ebay business. Thats what I do. If you know a lot about autographs like how much certain players autographs are worth, you can get some great steals on ebay. Then turn around and sell it for more. The key here is knowing how much autographs go for and not overpaying. Get the best deal possible.

If you want one that old, try a local pawn shop. If they dont sell things like that, the owner might know of someone who does. If its for a personal reason like a family member was in it or something, try writing to Sports Illus. they may be able to send you a copy
