Since joining the site, I've asked the same question. Recently, I've been talking to a lot of different people and I've found that (for the most part) the estimated price guide here is pretty accurate, especially for games that are bought and sold frequently.

Depends on the game and location. Some prices are more accurate than others. What game are you interested in?

When I agree with it, it's accurate. When I don't agree with it, it's inaccurate. Pretty simple.

The price range is based on past pinside sales.

Any price guide should be taken loosely because any number of factors--condition, location, sudden popularity, the release of new/needed parts, etc

The great thing about Pinside is that you can look for "Comparables" here:

Look for recent sales and adjust +/- for condition, mods and location.

What he said.

When I'm looking at buying a game, I check sales within the year. Then I look at comparable condition. If you want to get really accurate, watch CL and pinside for a few months. You'll notice trends with certain eras of games and you'll be able to pick out the top games and the dogs.

The price guide on pinside lags behind because it's dealing with a lot of lean years and prices are on an upswing right now.

all my games are undervalued on here

But yeah most are at least in the ballpark

whenever im looking to buy a new game, i search previous sale threads for that machine and see condition and asking price and whether or not it sold to help gauge a current price point.

I use Pinside to get an idea but never use these figures to buy or sell.

Add a couple hundo on the price if the machine does not need any work.

Prices are climbing...

Here is a summary of the last 44,000 pins that actually SOLD on Ebay in the last 12 months.

Some games only have a few examples sold, but when you have 32 TAF, 28 Playboy or 20 High Speeds, you can get a pretty good estimation.

You know the -Average- prices pinballs sold for on Ebay on your list are pretty fair, and actually seem "below market".
It is just such a waste of time as 99% of the pinballs listed on ebay never sell. I wish they would raise the BIN listing fee to 5% of the starting price for all auctions that start over $200... That would pretty much put and end to the constant fishing for a sucker that goes on there. You want to start at $1 with no reserve (and actually let the auction complete normally), sure list that for $2.00.
