its a good investment if your a fins or grimes fan. sadly sports collectible investments arent what they used to be as far as planning on flipping or making a buck off of. in the mid 90s i would say my sports card collection couldve netted a 1000 or more if i sold, id be lucky to get 100 and thats including my marino rookie card. heck at one time i found a drew bledsoe rookie card that was valued at $60 in a pack of cards. worth prob 10 cent now. i loaded up on autographed jerseys....have marino, clayton/duper, ricky, barry and bo. prob all worth a percentage of what i paid. but its all good, because when im gonna finally be able to do my man cave at my house they will all be on display.
so no its not a good finacial investment and you didnt over pay for a probowlers autograph on an official nfl football, but just know that the $50 has to be worth it to you because you're not gonna get that in return if times are hard and you are trying to sell it. it was for a donation so good job, youd paid more for the same thing buy it now on ebay. donations are always a great thing but its sweeter when you get a nice little surprise to go along with it
