Thanks for all of the replys. And they have made me somewhat wary. One of my alltime favorite films is Back to the Future. This poster makes a regular appearance on the auction sites, and habitually goes for around $150 (excluding one that was autographed by the Director and went for only $88 and that still puzzles me). I am not looking at this poster for an investment, but I don't want to buy a poster for $150 and have that value drop to around $40 after the 80's craze is over. So, I will keep watching and maybe snag one when the price begins to drop.
the day any of us can properly judge when an item is going to increase or decrease in value, will be the day I hit the Pick-6 and win $187million dollars
to go further, the investment value of a collectible is not in his sale value - if there is one - it's in the enjoyment you get from owning & appreciating the material
case in point
in 2001 I bought my Murder My Sweet 1sh for $3000. I've had the poster for 13 1/2 years or 4925 days. so for 60 cents a day for the past 13 years I have been able to enjoy this poster on my wall, which makes me smile everytime I look at it. As time passes, my cost goes down. if I'm alive in 2031, I will have paid $100 a year to own the item.
whether it has value at the end of that time is in actuality completely meaningless, because it was never my intention to sell the poster. So if it's worth $1 when I die, I don't care. In the investment was the spiritual investment, not the money.
going further
if a 1931 Dracula poster can sell for $310,000 on day and $160,000 next time - no Rosa, it is not holding it's value and by itself is an indication of the vagaries and travails of the business.
Movie posters is a hobby and unlike other hobbies, has been resistant to those things that make any market investible - there is no price guide. there is no central authority which would require people to adhere to a grading table that everyone agrees with. There isn't an easily accessible wholesale market (if there is one at all anymore). In other words, there is no central core, just many individuals doing their own thing.
This is unlike other hobbies like comic books, coins, stamps, baseball cards etc However those businesses are guided by a central core and all dealers adhere to certain standards in order for it to function in a cohesive fashion. At the same time, those hobbies are completely manipulated. Golden age Captain America comics have sold for double guide for years, why doesn't the guide reflect that? Simply said, the dealers won't allow it. When they submit their pricing each year for the guide, their conflict of interest is too much for most of them to suppress and their feeling is that if they honestly report those prices, it reduces their ability to buy from less knowledgeable people and make the profits.
CGC wasn't created by people just wanting to create a recognized grade scale - it was created due to a need to make grading even across the hobby so that wealthy buyers who were coming into the hobby were not getting shafted by overgraded comics, by comics that had unmentioned restoration etc and wind up leaving the hobby - taking their money with them. But what has happened is that comic books are now treated the same as stocks that you buy on Wall Street. It has been distilled down to it's basic monetary value and once it's slabbed, it's literary value is gone as you can't read the book anymore. It is just a representation of money
and then there is the aspect that - if you are looking for investments - that collectibles are not "liquid"
If I need money today and my ATT stock is at $35.47, I can get on my trading account, put in a sell order at $35.47 (full value) and I now have cash, instantly.
No so with collectibles.
You have a BTTF poster that is worth $150 and you need money today. Not tomorrow. Today.
where is the investment value at that moment? You can sell it and have the money in a few days, but if you need fast money, you have to take what-you-can-get and that's NOT going to be $150
so to boil it down.
if you buy posters, make sure you're buying because you enjoy them, not because you plan on making money because in all likelihood, you won't!
If you want investments.. ATT stock.. It pays a dividend
