Nothing pisses me off more than someone full of negativity and never suggesting an answer or remedy or solution to a simple question, like "what are the artifacts worth".
Since you are stalking and counting my posts, take some time and actually read some of them, as they are full of information on this from the beginning. (and I did provide my thoughts on the valuation) Just so you are aware, this subject is running on 2 different topics.
I see all sorts of valuations of shipwreck, $500 million, $1 Billion, and such, where it is very easy to determine the value is significantly less. Providing these types of valuations to the press of the public really doesnt help anything nor anyone.
A value of a painting by a famous artist, has little bearing on the value of the subject that was painted, so basing a valuation of a piece of incomplete stone on a painting seems a stretch. I see that Andy Warhol's Campbel's soup can is worth $12 million, does that make a can of soup worth $50 million?
When the subject of a traveling show came up, it was easy to note very relevant examples of said follies, especially the Odyssey Marine show, which at best made $3,000 for the month, and the Titanic show is in fact bankrupt. Is that negative or realistic?
There cannon and shipwreck artifacts everywhere, why pay to go and see more? There is a replica of the entire monument at a park, but one would go and pay to see a piece of one? Again, negative or realistic?
Because aside from stating a bunch of facts and info from other cases, and a bunch of personal interpretations of those facts and case examples, I havent seen you personally take a position
Well, that is fair, but why take a position, especially when details are unknown? Facts and case law from other shipwrecks are certainly relevant. What I do not understand, is when a salvor goes on a public forum, and vilifies the opposition, be it the legal council, the Court, the State, or a Country. Has that ever, ever worked in their favor?
In regards to the valuation, I really dont know how many artifacts their are, and of course, the identity is unknown. On the Cannon, the cost of conservation is significant, so I would consider the cost to recover, including legal fees and conservation. In reality, cannon are everywhere, so unless there is something very, very special, it is a wash on the cost. Getting paid for the recovery effort, well, there is that, but costs dont cover sweat equity.
On the column, so far, it looks like just on piece, not the entire column. There is little precedent for a column like this, so it is difficult to determine a value. Displayed a a piece of the monument would be of interest to whom? The Society has an interest, but really they dont appear to have funds for any purchase. Getting paid for the recovery, again. does not appear to be too much effort to raise it and not much to conserve it. The column was a snapshot in time, that has some historical value, but in reality, I see little interest, so that is why I feel it is worth less that $50 thousand. (recently the oldest known stone tablet of the 10 commandments was auctioned, was about 1500 years old, for $250,000)
The issue here is precedent, and the State of Florida and France are here to set a precedent, not on the value of the recovery, but on the value of the case law. Florida has rescinded the permit, and France has brought on Goold, so the stakes on the precedents are high.
Notable case law would be the Brother Jonathan, to which the salvors won against California all the way to the US Supreme Court, yet even though losing, California never allowed for a recovery permit, and placed the site on the Historical Register afterwards, thus preventing any further recovery and limiting sales of what was already awarded the salvors by the Courts.
Actually, I am a bit surprised they even let him in dressed like that. What was that hair slicked back with, and you want that on the glass?!?!? 
gloves? think about it..
