The reasoning behind my beliefs is that I have found certain marks relating to EITHER older Rosicrucians from 1600's, OR Templar Masons from the 1776 era's in Nova Scotia on some of these stones.
Some of them even looking specifically like George Washington's face leading me to believe they might have had to bring up the troves, and then to rebury them further away from the imposing British forces in Nova Scotia.
There is a theory they were there on the island collecting some silver and gold deposits for funding the revolution, and that they were informed about these troves by the Masons in the Grand Lodge of London.
There is a member here named Robot. His research extends into the Oak Island mystery with claims the founding fathers were bootlegging the whole affair with these troves.
If you have information to gather about their operations, you should contact him to find the correlating evidence showing Benjamin Franklin's involvement in the whole affair. It might be the link you are looking for showing that they had ALSO gathered the sacred items and placed them into vaults or tombs for a later time.
The other evidence I have gathered was the fact that the later organizations of the KGC in NYC, and their Mormon associates in upstate New York and Vermont were avid about trying to peruse the areas in Nova Scotia for these troves, to use them to convince their followers of their affairs, as being "Called by God" to follow the train out west.
They either found these troves, or were 'hired' to find these troves and hide them, on behalf of higher Jesuit authorities, who also possibly gave them the maps or locations to their gold vaults in the Superstitions, or in Santa Fe, to reinforce their operations
And.......
They were given the information from an insider in the Free and Accepted Lodges in the US, who had ties to the higher orders and used these troves for their own demise.
Albert Pike.......the 33rd Degree Mason, one of the founders of the KGC, and a keeper of a castle in New Orleans.
They were plotting to run a secret organization of banking moguls behind the scenes.
The Standard Oil Trust of the 1871 pact they formed was the Pennsylvania monopoly that dried out quickly.....
As the oil dried out they moved to making the gold theirs.
This Beale Story may be a part of the whole affair mentioned above, as being the crescendo to make the monopoly a controlling factor in the US Govt. I believe they may have gotten to the vaults and disposed of the goods in an area under their control.
Notice the marks on your DOI that show a hole singed around both the words 'Disposed To'?
There is a lake in Nova Scotia that looks exactly like the shape of your marks, and you did say the marks were intentionally made for a reason?

If there was a removal of an object from the Nova Scotia troves, and if this mark is found near Bedford Basin, NS, with another mark found in the Beale clues that show a Map of the area, with the same mark, using the same name Bedford as its source.
That is far too coincidental to overlook, as is the thought of Benjamin Franklin possibly editing your DOI and including his eyepiece and Key......
The Mark there in Bedford is also found in Bedford Basin, and is obviously a map to guide one to the items they "Disposed to" or dumped

Here is the mark that holds the Exclamation Point
And these mapped carvings actually lead to this point south of the Lake there in Bedford Basin,
