Open to find more pressing information?

After sitting on an inherited record collection for far too long, I am about to start catag over 4,000 LPs. My question is this: for a factory sealed record, what is better for its value -- to leave it sealed or to open it to learn more about the pressing?

Example: John Coltrane's SD-1361 will reveal 172 variations... (I think I narrowed it down to a 1975 reissue based on the album cover). Open it to learn more to confirm pressing or leave it "as is"?

As you're interested in value, this will probably be better off in the Marketplace section: https://discogs.sitiosdesbloqueados.info/forum/topic/262

Or general: https://discogs.sitiosdesbloqueados.info/forum/topic/1

Ah, thanks much ... just getting my toes wet before I start what will probably be a year long effort to catalog everything! Will post there.

Good luck!

In general a sealed copy is worth more than a unsealed one. A exception would be if unsealed to confirm a ”first press” or a specially sought after pressing.

A problem with selling sealed copies on discogs is that here you have to list it under the correct version and sometimes that is hard/impossible with sealed records. Wich can lead to negative and possibly other things.

Thanks -- as I am just getting my toes wet (have only added 2 LPs to collection, out of 4500, so far), my feelings were in-line with what you have stated. I would never want to be inaccurate with the LP pressing or its condition (and hopefully won't make too many mistakes along the way). My instincts tell me to leave a "unimportant" pressing sealed (as I believe to be the case in my example) and, only unseal (as minimally as possible) something I need to confirm to be a more valuable pressing. For the time being, I am just in the catag stage... selling might not come for a while!
