Colnect Item Score - UNIQUE FEATURE

[tcawe]

Announced on our blog - you can comment there

Following many deliberations and calculations we're happy to finally announce the unique Colnect Item Score that will help you determine the value of items on Colnect.

This feature is now free for all Colnect members but in the future may be limited to non-premium members.

Your opinions are welcome

UPDATE UPDATE UPDATE 4/March/2012

Please mind two new additions:

* You can sort any list by the score.

* Still not publicly seen but you can filter to see only items with High or Very high accuracy by simply adding

/min_accuracy/high

or with Medium and higher accuracy using

/min_accuracy/medium

to the URL you view.

Examples:

Highest scoring stamps with at least medium accuracy

Highest scoring phone cards with at least high accuracy

https://colnect.com/en/phonecards/list/ ... t/by_score

Highest scoring coins with at least high accuracy

Happy Colnecting

Now I can see the score without a second"click".

In the debate I have suggested, to list down collectors

in addition to quantity and ratings also by colnect scores (Quality of collection).

for example:

number of collectibles (cards, coins stamps e.t.c. ...) in the collection,

With colnect score 90 - 100

80 - 90

70 - 80

and so on.

PERFECT Amir, right as I suggested you a couple of years ago. Now each collector can know the real value of the asked card and the offered card in change. Have a good weekend.

Maybe it would be better if it was placed below the Description panel? Something tells me that its current location (Between Mintage and Denomination) looked a bit out of place... but that's me

Tu as tout à fait raison

[steamtrain]

I think the former place where it was , was a better place than this.

It is too much in sight this way, it is in my opinion an irrelevant fact for the item itself.

It does not say if all facts about the item are right.

I agree with Rubycored.

Hi,

In my opinion, for coins and banknotes - very not reliable.

First and foremost - The value depends on condition and year of issuance.

[tcawe]

talamnon - Soon I'll try to add sorting by score and more relevant statistics.

Rubycored - Thanks for the comment. I've lowered it to be just above the description panel. It doesn't make sense to me to have a one line field be displayed after the description.

steamtrain - Many collectors consider this score very relevant and it will continue to appear there. In the future we'll try to add more customization options to Colnect.

[Peti543]

Could you tell me why these two stamps have very different colnect scores?

https://colnect.com/en/stamps/stamp/195 ... cs-Hungary

Inventory: 1 collection, 18 wish.

On the other hand, here is a similar stamp with similar inventory numbers:

https://colnect.com/en/stamps/stamp/207 ... ce-Hungary

Inventory: 1 swap, 22 wish

There is little difference in the inventory but very big difference in the colnect score.

[morriemorrie]

I think and hope system could go perfectly in a few days , for the phonecards too.

[steamtrain]

Many collectors consider this score very relevant

Correct me if I am wrong, but this is how I see this rating:

As I speak mostly for the phonecards that should mean that a card that a lot of collectors do have in their collection and a lot of collectors that have the card for swap and a lot of collectors wish the card, the value of the card is high.

If there is a card that only 1 collector has in his collection and about 30 collectors wish the card, the value is low.

To me that does not make sense, it does not say anything about the value of the card or the description. A card with low print run should than never get a high rating.

Again if I am wrong please explain to me.

[tcawe]

Peti543 - thanks for reporting. It's a glitch that affected some of the items with very low accuracy that shouldn't have been graded at all.

steamtrain - yes, you misunderstood. More wish -> higher, more swap or collection -> lower. Add to this some other factors (that won't be published) to make the algorithm better and somewhat intelligent and that's it.

I think that goodness, approach and problems could be diferrent for each different collectible.

So I talk only about coins area. The score is very usefull to verify difficulty to find coins missing to collection or attractiveness of a double coin we have. But it can not be its market value: it is only an usefull tool to evaluated coins, only a rarity index similar. Both are good, infact index are similar. I have compared them for coins of many countries and values are similar. But Colnect score is a little better. Why? I dont know formula or algoritmo used for both index so I cant decide on formula applied. But I collect coins since 1970 and I know exactly what coins are more difficult to find to complete my collection and I know what of my double coins collectors frequently ask me for their collection. So I can affirm that Colnect score is more realistic than their index.

But both have a big difect, index depends by number of collectors of each country. Their collectors are mainly French (600 collectors) so coins of France and ex colonies are penalized and all circulating coins have low index. Same think happen to Colnect for spanish language countries. I.e. if you check Argentina (180 collectors) almost all circulating coins have a score below 25.

Score need a correction for countries which members is rilevant!!! It is easy that almost all collectors of France have in collection and for swap French coins and so on for Argentina collectors.

enrico - thank you for your input. Please mind the accuracy field is extremely important on Colnect's score. Low and very low accuracy scores are there only as a hint. Very high accuracy score is one you can trust. The bigger Colnect gets, the higher the accuracy of the scores would be. Interesting to learn that they have such an index. I went now to check it out but couldn't find it exactly. Is it the number under "get this coin"? I'm using chrome and see a number with a question mark that opens a popup window but it's blank... Colnect's algorithm is using inventory lists as well as collectors' reputation and possibly other factors in calculating the score.

[muroillo]

I think it is not really informative. each item has an own value only known by collectors in possession of the corresponding catalogue.

It is too much in sight this way, it is in my opinion an irrelevant fact for the item itself.

It does not say if all facts are right not even about the real value of the item.
