Welcome to Stamp Community Forum, vacillate! I just taught a young girl the meaning of "vacillate" yesterday!
Yes, you are right, we love to look at stamps, any kind in any condition, common or rare! So thanks for the pics!
I took a quick glance and here is my opinion --
1. The collection covers a broad range: mint/used/CTO, many different countries, perfins, precancels, cinderellas. The great majority is common. It looks like material found in $1 grab bags.
2. I did see a few stamps that catalog $1+, but the photo album is a stamp killer and retail value killer. Remember, the true value is in the collecting enjoyment, the history, and the variety. I didn't see any $10+ stamps in there, but I didn't check with a fine tooth comb. There's no way I can check for watermark and perforation varieties -- that's one of the reasons a dealer may charge appraisal fees. So there may still be some $10+ stamps in there, but those stamps often require physical examination/measurement.
3. To be honest, I think most dealers would not even make an offer for the collection for fear of offending you. Again, the main reason is because of the condition of the stamps and the use of the photo album. Sorry to be so blunt.
4. That is not to say the stamps are worthless or that other collectors would not be interested in those stamps. It is a profit issue for the stamp deaer. The are a few precancels (2 horizontal lines with the city/state between) that have additional commercial overprints that some people specialize in. I also see a few perfins. They may not be particularly valuable, but collectors who go after those items usually do not put condition as the #1 criteria.
5. Only one stamp really caught my eye. On page 7, row 1, stamp 2 -- the Great Britain 1c stamp showing Queen Victoria in the lilac color. The stamp is the common 16 corner dot variety. However, the cancel is interesting. I am not a cancel collector. However, most of these type cancels on the Queen Victoria stamps that are that style and in the format LETTER## usually have a small to moderate premium attached. In these special format cancels (not all numbers, but letter followed by numbers), the presence of the letter indicates special usage (such as Great Britain stamps used in overseas colonies). The number is associated with the city or post office of usage. I don't own the proper literature to look it up for you. But this is what I mean by -- the real value is not in the catalog/retail value, but in the history and enjoyment of the stamp!
I hope your friend will continue to build on the collection! And if so, then it would be wise to invest in a philatelic album for future additions and discontinue using the photo album.
