I consider my postcards as a treasure.
Me too.
TOT7S- Regarding how much is typically spend when buying a postcard.
Guess you have to take into consideration rarity and if you'll ever get another chance to purchase the same card again.
On the other hand if it's a common card and it will come back around then you can afford to wait for the best possible price.
The more you look at the for sale area your buying in, the better you'll be aware what is a good deal and what is truly a rarity.
IMO 5-20 dollars would be a price that I wouldn't hesitate on if I was really into the image but I have gotten some for as low as $0.15 that I would have paid over $20 for.
Also let me tell you these small amounts add up really quick if you can't stop yourself (I'm addicted and try to stop).lol
I agree with Regularjoe that if it's a card that is tough and the art moves me I might possibly go to $50 but not with thinking I could make that money back.
I'm not quite as concerned with prestine condition though as much as rarity.Comic book collecting has really turned me off to condition collecting when it becomes about collecting condition rather than about the significance of the item.
To each their own though and it's probably only human to want the best.
Generally I see a lot of great cards selling in the 3-10 dollar range but every now and then you can make a great score for under that.
Obviously,like anything art oriented, what appeals to one will not appeal to all.But this is an affordable and fun area of collecting if you don't go overboard.
