Hello and welcome! My name is Doris.
I have been an antiques collector, dealer and appraiser for over 56 years.
I will be pleased to help you.
Please see the following three images.
All three are signed baseballs that have been certified as authentic.
Please see the following service that certifies signed baseballs....
There are two baseballs in the following images that are signed by ***** *****. One is selling for $5336.99. The other in better condition is selling for $9748.99.
The other baseball is signed by Grover Cleveland Alexander. It is priced at $26,718.99.
Certification is necessary to obtain prices like these. I encourage you to do that.
A private seller to a dealer or at auction can expect 30-60% of retail value.
I hope I have helped you.
