Wish These Were 491's

Here are a few stamps and I have no idea what Scott numbers there are.
Any help appreciated.

They are Perf.10 vertical..All of them.

The 1847usa pages in Stamp Smarter have very detailed charts in color showing the various differences between the types. The image is too small to determine which stamps are type III (455 or 492). Massive quantities of type III coils were produced. Type II coils would be 454 or 491 but they and Scott 453, the watermarked type I coil are scarce relative to type III. A good magnifier, at least 10x is needed. I routinely use a 15x Peak loupe. Many stamp collectors lack a good magnifier. In addition to identification, a competent magnifier can be used for evaluating stamps. The 1847usa link:

I got a fun surprise today, in that a stamp that I thought to be a common 454 turned out to be a 491, according to the PSE certificate. Nice to have a little surprise like that once in a while!
