N173 Cabinet card- Joe Gunson, need some insight

[Poker 1 ab]

New to the forum and am in the process of moving to auction a n173 Joe Gunson card found by a friend that deals antiques. As seen in the scan below, the card is in pretty good shape until you see the trimmed bottom.

My understanding is that complete, the card is valued around $1000, but trimmed more like $500. Can someone confirm that?

I see there are auctions here, but I likely will run it on a different site unless someone here tells me this is the best place to do so. The site that starts with an e is obv the biggest place for traffic, but I will go where I feel the best place to sell at the appropriate value is.

Anyhow, just looking for some info on the card in relationship to value.

Here's the scan:



Thanks.
