Help To Identify And Certificate An Imperial Korean Stamp - #9iai - 1897

Hello.

I have an interesting stamp that I need help to identify and certificate It.

It looks like the same stamp that is available for sale on ebay or delcamp, but I think that I need an Official Certificate to know the real price. We know that there are many overpriced to sell...I don´t know the real value of mine.

Someone can help me?

Here is the Stamp:



I have the series but once the used one looks to be a valuated one.



This is the ebay announcement:

I'm no expert but my 2010 Scott shows your stamp as Korea #12 and the catalog value as $17. I don't know why the ebay item is $8000.

The ebay seller is claiming to have Michel #9IaI, which is the light bluish red color variety for the stamp. Either that or the seller has mis-read the Michel listing and meant to list it as #9IIaI. Hard to tell colors from a screen picture, but it is likely the latter.

Either way, one would probably need a certificate for #9IaI. The last 3 of the 5 pictures in the ebay seller's listing are not showing up for me. I wonder if the seller has a certificate that is not showing?

To me, my stamp is much more red than maroon...
