How prices work

Every price comes from a public crested gecko listing on MorphMarket. A scraper reads the listings and records the price, morphs, sex, age, weight and seller. Each listing card on this site shows when it was last checked.

Prices are in US dollars. The small share of listings in other currencies is left out of price math so a Canadian price is never mixed in as if it were USD.

An asking price is what a seller listed the gecko for. Most numbers on the site are asking prices, because every listing has one.

A sold price is the last asking price we saw before a listing came down. It is not a confirmed payment: a buyer may have negotiated, and a few listings come down for other reasons. The sales history covers May and June 2026.

The price check narrows from any crested gecko to one described animal:

1. If at least 5 listings match the morphs, age and sex exactly, the estimate is the middle half of their asking prices.
2. If fewer match, it starts from all listings with those morphs and adjusts for age and sex using how much age and sex move prices across the whole crested market. A car pricing guide adjusts a base value for options the same way.
3. With no age or sex picked, it uses all listings with those morphs.

The page always says which of these it used and how many listings it rests on.

Each box is the middle asking price for one stage of growth and one sex, with the middle half of prices underneath. Age comes from the listing: MorphMarket's "Baby" is shown as Hatchling. A box with fewer than 5 listings says "Too few" instead of showing a number that could swing on one gecko.

The growth chart groups listings by weight (under 5 grams up to 50 grams and over) and draws the middle asking price for females, males and unsexed geckos. A point is only drawn when at least 6 listings back it. When a morph has too few weights listed, the chart shows all crested geckos and says so.

For the morphs you picked, each row is the middle asking price of listings that also carry one more trait, next to the price without it. Only traits on at least 5 such listings are shown. This is a comparison, not a guarantee: geckos with more traits often come from stronger lines, so part of the difference is the breeding behind them.

"2.1×" means the morph's middle asking price is 2.1 times the middle asking price of every crested gecko listing we have seen. It puts every morph on one scale so any two can be compared.

Every listing is compared with similar geckos: listings that share its most valuable morph, at the same age and sex. If fewer than 8 such listings exist, sex is dropped, then age. A listing with no morph tags is compared with all crested geckos of its age and sex.

"Low for its kind" means cheaper than three quarters of those similar listings, "high for its kind" means pricier than three quarters, and everything in between is "typical price". "Best value first" sorts by the price divided by the similar listings' middle price.

Car sites call this a deal rating. Gecko prices spread far wider than car prices because listings never measure pattern quality, color or lineage, so a low price can also mean a plainer gecko. That is why the site reports where a price sits rather than calling it a deal.

A breeder's pricing is the middle of their listings' price-to-similar ratios. Under 0.9 reads as "below similar geckos", over 1.1 as "above", and in between as "in line". It needs at least 5 priced listings and only covers listings that name their store. It says nothing about gecko quality, health, shipping or service.

Every time the scraper reads a listing it records the price. The trends page groups those records by week and shows the middle asking price, how many listings cut or raised their price since the check before, and how many listings went up or came down.

Weeks the scraper did not run are left blank, never shown as zero. A week that checked less than half the market is marked partial, because its price rests on a small sample. New and came-down counts only appear when the week before was also a full check, so a restart after a gap is never mistaken for a wave of new geckos.

The scraper skips re-reading a listing whose price has not changed since a recent full read, and still reads every listing in full at least every six days. That keeps each listing in every week of the history without re-downloading the same details daily.

The markets page compares asking prices in the United States, South Korea, Japan, Europe, Canada and the United Kingdom. Korea comes from Feedle, the main Korean reptile marketplace, and Korean breeder shops. Japan comes from Repsuki, a search site listing stock from Japanese reptile shops. Europe comes from terraristik.com classifieds and MorphMarket listings in euros. Canada and the UK come from MorphMarket listings in their currencies.

Every price converts to US dollars at the exchange rate stored with the latest scrape. Morph names are matched in English, Korean and Japanese, and a name inside a longer one (Harlequin inside Extreme Harlequin) never counts twice. A morph is compared only when both markets have at least 8 listings of it and the gap is at least 20% of the US price. The gap is room for shipping, import fees and losses, not a profit.

Morphs are grouped by how they are passed on. Genes (Lilly White, Axanthic, Cappuccino, Sable, Phantom, Empty Back, and the emerging Soft Scale and Hypo) follow predictable inheritance. Patterns and colors are line-bred over generations. The genetics follow the Geck Inspect genetics guide. "Emerging" means only a few breeders have documented it so far.

• Seller questionnaire labels that are not morphs, such as "Diet: Meal Replacement" or "Proven breeder: No".
• Prices of zero or over $100,000, which are placeholders or typos.
• Group lots, from the sold price bands.
• Species other than crested geckos.

• Pattern quality, color intensity, structure and lineage move real prices a lot, and listings rarely describe them in a way that can be measured.
• About 4 in 10 listings carry no morph tags, so they count toward the whole market but not toward any morph.
• Not every listing is rechecked every week. The data status page shows how current the catalog is.
