Baseball Series 350

These cards are from the T206 series. Looking at these cards, most of them appear to be smaller player names and not All-stars . Your cards appear to be in fair condition. What increases a baseball card'a value is if there are pointed corners, the color is not faded, no water damage, no creases, and if they are graded. Your cards are not graded but most if the cards graded would fetch a 1 or 2 grading, maybe 3 if your lucky but it is very hard to find cards like this with a grading above 5. The ones graded above 5 with nice color tend to sell for $75, If it is a known player most can fetch hundreds but you don't appear to have any stars and the cards are in fair shape but I think if you wanted to sell them, you could fetch $15-25 a piece but at the price, honestly I wouldn't sell them. Hold on to them and keep them well protected and those cards could be worth hundreds. I have many T206 cards that I have bought and most I have got around the $10-$20 range. Your cards are nice with color but most the the corners are rounded, pieces of the cardboard are missing and some creases and wear to the card but they are not in the worst condition so I believe you could find a buyer for $20 a piece maybe $25 if you find the right person. 

I don't think this was the news you wanted to hear but hope it helped
