Anybody who has a collection of Vinyl where Classical is a large proportion there are a large Populus of enthusiasts across the Globe of this Source Material, this Genre has interested parties with substantial disposable income, they are very content with ownership of difficult to find recordings.
More Importantly there are very very valuable pressings, where £300 - £400 - £500 is the common seen price.
Then there are the £1K to £1.5K pressings that are sitting in a collection.
I can't reiterate more, there is a time to draw on the Families Support and get a List of what Titles are owned first, and then more importantly get the EAN number matched to the Title.
Approx' 8 Years ago I assisted a Widower by buying a few items her husband had in the remains of the audio system, a dealer had taken the main system at stupid monies, and was sure to do well.
The Dealer also offered stupid monies for a Classical Vinyl Collection which was turned down.
I passed on the same advice as stated above and at a later time was informed after only a short period of investigation LP's were found to have a Value not much different to the lower priced ones mentioned above.
For all I know the widower I helped may have a sale value recorded in the the following list in the Link.

The Link from Discogs shows there are 750 items descending in value before the sale price is near £1K and near 2000 descending in value to have a sale price near £500

If an LP owner wants to give those opportunities up to remunerate themselves for preserving their Vinyl Collection for so long that is fine by me, and the Carpet-Baggers making silly offers.
