I was just reading a SQ book I bought recently and the authors say that there is very little between the copper red and Indian red. If there is one, it is very, very slight. They both occur in the early (1870-71) first Ottawa printings at the same time.
Based on the samples I have of the early printings, the stamps you have are definitely not the copper red/Indian red of the early printings. For one thing, they should be much lighter in tone.
As far as what you see for sale, unfortunately, many sellers mis-label small queens; often they are really just guessing, and of course will lean toward the more expensive items when they do so.
The best solution is to buy some good reference items from a reputable seller that specializes in this issue.
I will eventually be doing so in my
ebay store to help those collectors that are going through the same struggles with identification.
I mentioned in a different thread, that I have been working on this myself for over a year. It is a complicated issue, often made more confusing by sellers that don't really know what they are selling.
