Hello BrianLevancy, welcome to Stamp community!
CAUTIONIf the 1/2c Black Queen and King stamp, the 2c brown side-faced King Medallion stamp or the Greenish 5c Registered stamps are new with no cancel and have gum or shiny on the back, do not soak these in water. That would ruin the value of them mostly.
The used, cancelled stamps DO please try to soak or float them to clean them up a bit.
Most of your stamps shown are dirty, that is, have years of dust and grime upon them, OR are infected by mold possibly also - note the black edges around the stamps' edges - this Could indicate a mold or mould problem, which is also known as rust or browning.
I understand a cleaning in only warm, slightly soapy water (mild dish soap only, not much) will help clean up the dirt or grime (Not the nice cancels and postmarks though!, they will be OK) on older stamps.
You do not have to worry about any of those stamps being of an aniline ink manufacture (the ink runs in water) as only one Canadian stamp was that way, a $1 purple one, and only some of those at that.
I like some of them personally, the colour shows good on some, the cancel on the blue 5c King George 5th (KGV) is nice from VANCOUVER / BC but the year date is hard to see.
The 3c Queen Victoria (QV) is faded a bit but looks very nice just like it is to me, with the partial Saskatchewan (I think) cancel on, a duplex type, as it has the killer or obliteration part included. Nice to see that.
The KGV Admiral (dressed in an admiral uniform) stamps are nice also.
The 12c blue Map stamp has the top straight for possibly two reasons. Hard to tell from that picture. It could be a edge-of-the-pane stamp and just come that way, or it could have had the perforations (holes around the edges or wiggly bits) cut off by accident. Get a picture of the back of it laying on a dark surface and we can see from that perhaps.
The dirt will clean but the possible mold (may be just the camera angle and lighting you choose that makes them look that way) may not come off and can infect other stamps if not separated from others and treated with care or thrown out as some here would recommend (including myself).
The album or book they are in should be changed also, as that may be dirty.
Pricing, if that is of a concern at this time, can be found in a Scott or other name catalogue, in a library most likely, or for these older stamps, from a used older catalogue.
The stamps with nicks and cuts and pieces missing please still keep them as examples of colour or perfs (perforations) or paper or even an example of a damaged higher catalogue value stamp.
I see in the second picture a very rare stamp at the right hand end of the first row. The 50c black Admiral War Tax overprint stamp. Please be very careful with that one.
Please show a better picture of it also, I haven't seen one in real life yet myself, and only a mint (post office fresh) one on Stamp Community (SCF) here. These are found in the back end of the Scott's or Unitrade catalogues by the way, under War Tax stamps, under MRxx numbers.
Possible 2005 (what I have) Unitrade catalog (cat.) value is CAD $100.00 as it is (or looks to be maybe) a Fine (F) grade stamp, not a Very Fine (VF) grade one. Neat!
The 2c brown War Tax 1Tc (1 cent tax) stamp below that one is not as valuable but there are two versions, look at the lines below the 1Tc inside the oval and the catalogue will tell you which version it is.
The Queen Victoria QV 1/2c black has a nice camcel on it and is, I consider a Very Fine grade stamp, looking only at the front of it.
All stamps should be looked at both sides to see any possible damages or pin holes or creases or whatever, as some people will not balue these as highly.
Clean 'em up and shows us again some time. I will be happy to relook at them anyway, fronts and backs.
