How can I identify signatures if there are no pictures of them?

Hi,

This concerns the 20 dollars banknote of Guyana: 

I identified its pick number by its measurement being 156 x 65; it's P#24.

However its variant is difficult to determine because there are no pictures of the signatures provided on the Numista page: N#281791

I've attached an image of my Guyana 20 dollar banknote.

Any help is welcome.

Regards,

Benedict

I think it is P-30f $20 with the Ganga & Singh signatures. I always first check the serial # prefix (yours is C/65) & the variable sized serial numbers give it away (whereas P-24 has all the same sized serial numbers). I then start looking/comparing what I have to the notes in the catalogues. If the prefix doesn't help then I turn to the Banknote Museum for the signature.

Great! Thanks. I will bookmark the Banknote Museum. Great help.

I looked at this page of the Banknote Museum and I think it's the one below the one you mentioned, namely P#30g. That's the only one where the signatures match. But then the size of the banknote doesn't match. If I look at the size then it's suppose to be P#24. Somewhere there must be a mistake; on the Numista page or the Banknote Museum.

I wouldn't pay too much attention to the sizes in the Numista catalog.  They both are probably 156 mm X 65 mm nominal. There can be small variations in actual cut banknotes. Whoever measured the P# 30 probably had a somewhat small one (or just measured slightly off).

As an aside, this has no business being in a Catalog:

None of those signature numbers are defined anywhere so they are useless.

Okay
