>There are lots of way to "mend" a note. I am sure that there are invisible
archive tapes that might be used. But is this acceptable? Or is it just
another kind of "scotch tape"?<
There are archival tapes used, but none are invisible and are allowed or
encouraged to keep a note intact. Cellophane tape is of course the worst thing
you could ever apply, but that faux pas, much like Brasso on a Morgan, is
unfortunately usually done so at the hands of a non-collector. Ditto the
sacrilage of starching and pressing notes or "any" kind of cleaning. Does it
occur? Of course, especially with high end US large notes (those of the period
of 1862 through 1928).
Unlike a coin, a note can be extremely fragile for oh so many reasons. On many
19th century obsoletes, the paper stock used was the sheerest onion skin bond
you can imagine, instead of a heavier stock. Even with heavier stock notes, the
note can be selectively worn or more often torn, at certain points, not others,
so that means the thicker portions must become bridges for the thinner ones
because salvation of the whole becomes paramount.
Some notes are just fragile to the touch, almost to the point of being brittle
and you'll never know why.
John Stone touched on the basic principle of most PM collectors and that is, we
have to take what we can get, because often times, there is nothing else better
coming along around the corner. It's not at all uncommon for collectors to have
SENC (Surviving Examples Never Confirmed) notes in their collections and NOT be
Rockefellers or Gettys. That is just one reason why this hobby can be so
compelling and fascinating. How many coin collectors you know, can make the
Sub divisions of this rarity status may include whether or not a note was
issued, i.e., signed or was simply a remainder or an unsigned, though obviously
existing example. I can't tell you how many times the difference in price paid
by me, between issued and unissued, could be hundreds of dollars and on a
higher order, thousands in certain cases.
Authentication of signature, provenance or even issue becomes a problem
sometimes and "we" do not have the luxury of an ANA or other arbitration. We
only have other collectors. Fortunately though, many bogos of the 18th and 19th
century, can be spotted a mile away. Some are tough.
I'm rambling.....Time to snore.
