Gilbert MainesGive yourself a chance.
You can make this determination without relying on the slab houses!
Purchase the David Rudd Cycleback book entitled "Judging the Authenticity of Early Baseball Cards"
It will probably cost you not much more than one PSA submittal, and it will empower you for the rest of your life.
I am serious.
If there is anything which you do not understand, please ask me, and if I can not handle it, others here can (including the author).
The book is typically available on eBay.
If you can't find it for a while, check the Internet search engines.
