Intact horses versus altered horses definitely have a huge difference in value, considering breeding is the main aspect of the game. Altered horses are still valuable, however, because of the point system (The more competition points a person has, the more their show bonus is every week).
There's nothing really to do especially with different Eras. It's been a while since Era 3 started, so thr last Era 2 foundations were born a while ago. A very old mare only has a few breedings left in her, so she's not as valuable as a much younger horse who happened to be born after the new era. Eras are also inherited by foals, but the value is more to do with generation than when his/her first ancestors were born. :) Eras were mostly created so that some of the leaderboards wouldn't be dominated by some players who simply have been playing longer than everyone else.
Do you color test them? Certain genes can definitely raise the price. Appaloosa I think is getting pretty popular, so a price-raise is fine there. Flashy white colors on a horse can be caused my lots of different genes, so depending on which ones (some are buy-only), they can be really expensive.
I also usually add small tests' prices to the sell price, and less than the whole price of the larger ones. :)

If you're looking for show horses, however, you want high PT scores & lots of all time points earned. Which means mature horses.

With mares and stallions you might also want to check the average PT of their foals.

That said; Brindle has always been desirable, I think. Pearl and Satin are pretty high on the list. Galustra Plume is right up there, and current 'fads' (at least from my point of view) are DP, liver, and 'black' chestnut. Splash and Frame are in the middle. Those genes, on top of your shiney appaloosas, will increase the prices you can get.

Drafts and Riding horses are relatively new (in the past year, is that correct, ladies?) and are still kind of 'niche' markets. (If that is all you're marketing - a draft or riding horse with the fancy genes is gonna be very valuable to the right person).

Pricing is tough. Untested foundations are only worth 2500. Even if you've done the free testing on a foundation horse, you probably won't get a much higher price for it without the fancy genes (Which are REALLY hard to come by on a foundation horse). Higher ranked foundations (High level herd helpers, and Rank Specials - the ones Ammit comes out with a couple times a year, like the recent Freaky Friday) are worth quite a lot, however, because they have extra benefits - perfect breeding ability, higher PT scores than a regular foundation, great show horse abilities - not to mention the fancy genes. A sixth generation stallion that is known for passing his one fancy gene and decent PT score could be anywhere from 10k to 100k. A gold papered mare with 77 fancy genes is going to be millions! (Are there even 77 fancy genes in the game?!)

Ok thanks everyone!

KerredansCorral has given good advice for horses that are no longer adding points to their show score when you train them. Other horses, give them a few weeks chance to improve.
