Hi Gordon,
  I'm afraid I have no good news for you.
  A sheet is considered a sheet when all stamps are in tact and attached.  If they are detached, it's no longer a sheet.
  What's worse is, you've now also ungummed all the stamps.  This will plummet the value of the remaining stamps.  Even the plate blocks that you might create out of the remnant will have about 1/10th their catalog value.  Stamps from this era are valued with full gum in tact.  There are hinged values, but no "No Gum" values as there are with earlier stamps.  A stamp with an adhesion is better than a stamp with no gum... so soaking it immediately destroyed its value I'm afraid. No Gum stamps from this era are basically the same value as used stamps.

I guess the best thing here is, chalk it up to experience, and realize that anything that removes/further degrades gum is not advised...

My expertise is in US, but I have a lot of exposure to worldwide, and with wide reference material, I will do what I can to answer questions about global stamps. In US I have extensive experience in all aspects (does include Administrative overprints for Cuba, China, Puerto Rico etc.). Also, Hawaii general issue and Revenue (pre-statehood). Of course still building knowledge but have been collecting since 1980. Air Mail is a favorite area, but not a limitation. Two specialty areas are Large Banknote issues, and Washington/Franklin identification. Strong experience in Carrier & Locals, Private Die (Also known as M&M for "Match & Medicine" but also includes some playing card and perfume stamp issues.) Recently have been building more back-of-book experience, especially around Official, Newspaper, Revenue and tax editions. Some covers, and cancellations, but not my strong suit. Another area I'm recently diving into. What I can't do: Anything non-US, as it's just not an area I focus on.


30+ years of learning the hard way. A lot of passion for collecting and dealing (as I do both). I don't consider it a hobby... I consider it a serious pursuit that I'm able to do in the hours I'm not occupied by annoying things like sleep. I work closely with some of the global leaders in the expertizing and identification field. Have co-authored several papers (with Mr. William Weiss Jr.) related to identification, as well as tool set to help with quickly identifying the more challenging areas of Washington Franklin. Strong experience in paper types and coil validation.
