Trying to gauge the rarity of my Ooyama’s Pikachu vending sheet

[BrocksNoseBleed]

I recently traded for a large vintage box of Pokemon items. And I got 18 un peeled vending series sheets.
I didn't even pay attention to which ones specifically were in the stack but I got one I think it's pretty uncommon.

Series 3 sheet 2. The Ooyama's Pikachu sheet.
I really don't want to unpeeled it. It would be awesome to have the whole sheet preserved in some way.
I have doubles and triples of a few so I did plan on peeling a few because I collect these.

Any input would be appreciated.

I'm new here and I'm an old collector. I've been collecting pokemon since I ripped a Cardass pack as a kid.

I've got to be honest with you bud, I have zero idea about this stuff. I'm not sure many in the wider TCG community will. I know there's people who are really into the vendor card sticker sheets, perhaps trying to find a discord or reddit community more focused on that will yield you some better info.

I did find a few results on google, not many, but the mentioned sheet was sitting around the £60 - £150ish range. As I say, I know very little about the vending stickers so no idea if this price range is actually correct.
