I would like to be able to search a store by rarity of number available. Then,
I could get the least common parts a store has to offer.

Opinions?

I like the idea. Often a store offers rare parts which are not on my wanted list.
But it is hard to find them. With this feature you can make a fast choice to
buy them for example to meet the minimum amount.

Yes, it woulg make more sales for stores that offer "rare" or "HTF" parts, without
them having to say "Rare" or "HTF" in the description. Also, it would filter
oy non rare, but marked as such in the comments

What about an option to filter for non-production parts, the rarest of all parts.
That seems easy enough: a filter that shows all parts which are listed as colors
that do not appear as their known colors. That would become tricky when parts
are make in new colors like the series 6 accessories, but would be sorted out
once added to the catalog.

Why are non-production parts "the rarest of all parts" ? There are non-production
parts that are far more common then some released in sets.

mhm i don't really like this idea, because the market of rare items can be cornered
by one seller at ease then. on this position the seller can try to dictate the
price as he like it cause he is the only one offering these parts. this will
raise prices for the collectors who need this special part for completing a set
without any reason and may force them to look for the item on alternative sites
(BL looses orders).

my 2 cents summary

I'm not sure I understand. Sellers are already able to do that. (I suppose that
the suggestion would make it easier for sellers to notice they have rare parts
if they are unaware.)

yes the can do this on limited basis yet, but it requires some experience and
afford to do this. i think with this function it would kind of to easy.

It's an interesting idea. It could certainly be useful.

There are a few things that come to mind that might make it difficult to implement.


The first is that "rare" is fairly vague. Presumably, a part's rarity would be
determined by some comparison to the total number of that part available on BrickLink.
But for a computer to do it, we need to be very specific about what is being
checked. Is it just a count of units? If a part has fewer than X units available
across BrickLink, it is considered rare? And would we take into account six-month
sales? Is a part rare if there are only 10 of them currently for sale, but 500
of them have sold over the last six months?

That might be the simplest implementation. I could see something added to the
advanced search page inside a store. A slider or a text box when the user enters
the number X.

But I'm not sure how accurate those results would be. If a store is the only
BL store with a particular part, but they have more than X of them, the calculation
wouldn't consider the part rare. We could subtract the number in the current
store from the calculation, but this could still miss parts that I would consider
rare.

As an example, there are sometimes sellers in Germany who get large numbers of
what I would call rare parts. Let's say I have one of them in my store, and the
German store has one hundred of them (and that is the total extend of the BL
supply). If we want this part to be considered "rare" by the search, the method
described above probably wouldn't work. (It's possible, thought, that you would
disagree that the part I describe is rare, if there are over 100 of them.) We
would likely need to add in something about how many different stores have the
item. But this seems like it would get messy.

I think that the search would likely return a lot of parts that fit the criteria,
but which aren't actually "rare". Galidor parts, for instance, aren't commonly
listed. But are they "rare"? I wonder how prevalent this kind of false positive
would be. If they are not overwhelming, the user could just "see past" them in
the results.

Having a user-selected value X for the calculation is a bit awkward, though.
The user might have no idea what to put in. Perhaps a better solution is still
to return all the parts in the store, and just SORT them by rarity. This might
be the most powerful solution because it could be used in conjunction with arbitrary
text search results and browsing within categories.



I wonder if some sellers might be put-off by the idea. Right now, there isn't
an automated way of doing comparisons between stores from inside of a BL store.
A common request is for a price-check. Clearly, many sellers would not want a
price comparison tool, that checks prices in the store against prices on BL as
a whole. Would there be any pushback around a rarity comparison? There would
likely be less resistance, but it still has to be acknowledged that the idea
IS a form of store comparison (assuming that the method of rarity calculation
is what I describe above).


There are also probably technical constraints. I have no idea if the database
is set up to be able to quickly find the information needed for the calculations.
Right now, there are searches that allow you to find the total number of lots
and the total number of units for any arbitrary search (http://www.bricklink.com/storeFilter.asp),
so at first glance maybe this isn't a significant limitation. But the the suggestion
would involve running a similar search for each different part in a store, which
would be pretty slow. There would likely need to be a rarity index added to the
database, so that rarity calculations wouldn't need to happen on the fly.

I think this is a great idea and it wouldn't be to hard to implement since the
info already exits on BL.

My thoughts are...

What would be considered rare?

I would suggest go with a standard already used on rebrickable, which I believe
if a color of a certain part is found in 5 or less sets it is considered rare.

As far as non-production parts I would not include them. The reason is it would
be extremely easy to defraud a buyer, at least in my option. Unless BL is going
to verify and approve the part through the Catalog Add or Change system that
it is a actual non-production lego. Just simply listing the part as a color that
isn't already known should not add it to the rares.

How would a buyer find a rare part in a sellers store?

It would be automatic. After a seller uploaded a parted out set that had a rare
part in it under the "Show All Items" link in stores it would say "Show All Rare
Items".

Occurs only in 1 set from 1988 . But not rare by any stretch of the imagination.

The problem with that part is that it has a low demand so it doesn't sale well,
not that it isn't rare. So you having an extreme amount of them has no baring
in my option. Simple lowering the price significantly might create a higher demand
and you wouldn't have so many. But you may not be able/willing to do something
like that because of factors like how you acquired them and the amount you paid.

Also if this was implemented it would bring more attention to that part through
your store which would help you sell them because buyers would know they are
rare, even though you 100s of them. And soon enough that part would dwindle down
and become rarer with each new purchase.

I would like to have such an option too.
For me in buying but also in selling.
For instance: I have dark purple halberds, probably a one of small production
for a prototype Kingdom minifig. But if very few BL members search in 'parts
minifigure weapons' in my store no-one is going to find them.
