About estimate value price - banknote

Hello all,

i wonder why a banknote can have an estimate value for grade XF or lower as an example but no value for UNC or vice versa. I saw some notes that can have a value for few grades but not all. 
and some banknotes have no value at all under any grade. how this can be possible?

besides, what about current notes in market, it is possible that it doesnt have any value on numista? I mean at least it current market value.

thank you in advanced. have a great day

If nobody/not enough people claim to have on in this grade and/or don't enter the buying value there will also be no value on Numista.

Those don't come out of thin air after all.

On ebay prices are way higher that what is claimed by Numista users if thats how the estimate value is calculated

i started to enter the buying value for my collection

I hate to “dis” eBay b/c that is where I started to re-build (upgrade) & shape my Bank of Canada collection 20 years ago.  But you needed to know your Charlton catalogue estimated Book Values (BV) if you were collecting CDN notes. We called these BV's estimates only & they were often high for some series (low for others). Some collectors took their catalogues to shows/auctions b/c they needed to be able to correctly ID the coin/note & get a ballpark BV. Back then, eBay was more Fair Market Value since the majority of listings were True Auction style Listings (TAsL) rather than Buy it Now (BiN).  The market determined the value so often collectors started marking up their Charltons with eBay auction results.  Back then you could re-list your duplicates (or notes you wished to get rid of) for relatively low listing fees.  The thing is, we all knew that the pricing tables were idealistic for certain items (like modern day insert replacements for example) but conservative for older series (1935/37).

Today it is a much different market & high listing/seller's fees haven't helped. Today, most long term collectors refer to the platform as “planet eBay” because there's a lot of the coins/banknotes listed which may have the following problems: misattribution (incorrectly identified with the incorrect code), high price (due to the high fees) & over graded (the worst, most common problem) unless certified.   To make matters worse, the majority of items are BiN (not TAsL) so you get an even less accurate idea what a note/coin is worth.  

I started collecting world notes more actively around 2017- 2018 & I purchased a SCWPM (Standard Catalogue of World Paper Money) or “Krause” catalogue. These were the guys who started the K-codes for banknotes but went bankrupt & no longer publish their massive book. Anyway, I discovered that this catalogue (& BV's) was even more dated (inaccurate) than my Charlton when it came to accurate BV's (& a few sketchy descriptions of notes) but it was still a very helpful starting point.  

Today, it is understood that most BV's are simply a starting point for a certain buyer.  You have to take any “price panel” (whether it is online or printed in a catalogue) with a grain of salt.  Hope that helps!

Thank you Serial, your reply make more sense and clear few doubts i had. But what i dont understand is why a banknote with grade VF is priced lets say 1 dollar but UNC is not priced. shouldn’t be like a formula that a banknote looses 20% of its value with each lesser grade for example ? bc the rarity of the banknote here is not an issue, since there is a price for a VF grade, or it is purely supply and demand that decides the price ? 
i guess i will auction my whole collection once im completed and have few banknotes and coins for each single country in the world

From an earlier post by Xavier:

Why I can't see any values?
Values are mainly based on the collections of Numista users. No price is computed for a given coin, date and grade until at least 4 users enter a price for that date and grade in their collection.
Until there are enough data, and in order to avoid too biased values, no value are displayed yet, replaced by a dash.

How are the values computed?
The value of a coin for a given date and grade are computed as the median value of the prices entered in Numista user collection. Not that a user cannot contribute more than once to the computation of the median: if a user enters several coins with several prices, only the median value of the prices he/she entered is taken into account to compute the value.

Some auction prices are also used but primarily they are based on what users input.  There are also some adjustments going on (values of lower grade should not be above higher grades) but, as far as I know, no values are shown if there are no/not enough user inputs.  Values are based on the median of the data so as to not artificially drag the value up/down by outlier values.
