Already got it mate. Well, I have, but it's got a big newspaper print stain down one side which has never fully come out.

The shirt in question is the 2005 home shirt, not the NRC Final shirt. They were both very similar shirts, but this one (with the 1980 player names on the sleeves), was worn for the full season, whereas a similar round-necked one was brought out purely as a one-off shirt for the final. Now, the shirt in question will have been released and sold in decent numbers (for an NL1 club as we were), whereas the NRC Final shirt was limited edition and so presumably only 200 or 300 were made. I bought the NRC Final shirt for £25 from eBay in (I think) 2010, then decided to sell it a year later only got the same back. So, in my opinion the shirt the OP's friend is selling is not really worth a great deal because like I said, it is only the 2005 replica home shirt, not a limited edition shirt (same as you can get a 2005 Hull FC replica home shirt off eBay for £10-£15 max).
If I was the seller I might have held on to it for three years so that they could advertise it as a decade old, but as it is if I was selling it I'd be happy with £40 to be honest.
I tell you what is more rare IMO - in 2004 we brought out an all-red shirt for the Arriva Trains Cup Final against Leigh, but strangely the team didn't end up wearing it on the day. That shirt I would say is quite rare (it was made by Kukri). I bought one for a tenner off eBay maybe seven years ago, and got £35 for it at a later date.
Over the last few years I've loved seeing the retro reproductions that have been made (inc mine and East Hull Red's Hanson White project ), but would love to see a reproduction of the white with red band and white with blue band cotton Riding Bitter shirts that we had around the time we moved grounds (the ones with the HUGE v-necks! ), something about them shirts I just love, even though it was 4-5 years before I started going.

the shirt in question says limited edition around the badge, i would post a pic of it but dont know how to ebay link here if it helps Roofs

Just noticed the amendment to your listing saying only 200 were made. Again this is incorrect - the NRC Final shirt of the same year was only produced in 200 or 300, but for the shirt in question you are talking at least 500-1000 made I'd say.

no not at all mate thanks for the info much appreciated, she just doesnt know much about rugby and wanted me to ask on her behalf.
Thanks again and may the best team win come monday 23rd.

No worries. Again it's a very nice shirt, and if it hadn't already been bid on I would have perhaps advised her to maybe hold on to it for a few years. It was pretty well made, and on the pitch signalled the start of the rebuilding of the club, so holds good memories for Rovers fans in some ways.

Absolutely, should be a cracker.

It's a horrible shirt, but I love Roofs.

I've never met him but look at his advice!

Such a cool guy, Should post more but his shirt collection takes alot of collating.

Hmm, not sure I'd agree with 'Horrible' mate, eg it was better than last season's sache effort surely?!

Yeah I've kinda took a back seat on here the last 6-12 months. Still love it though, better than hullkrfans (with all its cliches and politics) any day.

Wish I'd said hi to ya at headingley last year in the rain mate when saw 'GOOSE POWER' a few steps in front of me but had a bad feeling at the time I'd upset / peed you off over something on here so thought better not.

Yeah I guess it was okay after the initial shock!

Hey so what happened with the shirt rowdellhead? I noticed it ended without anyone matching the 99p starting bid, did she remove the auction and take the £40 offer?

The ones I mentioned in a previous post that I thought were cool from 1990 (the cotton Riding Bitter ones), there's actually one on there ending today at nearly £40. Looks very smart but not bidding personally, have bought a few old ones over the last 2 or 3 years and there's only so many chances to wear them eh (as smart as it is).

Was going to say i see alot of that shirt worn so must be plenty about and as roofs has said not really limited edition.
Ive also seen plenty of the GF one you mentioned roofs but i cant find many of the one which had the northern rail cup winners tag stitched above the badge.

Weren't the Cup final ones actually wrongly embroidered with 'National Rail Cup' around the badge?
Can't be bothered to get mine out and make sure but I could've sworn it didn't say Northern Rail Cup.
