Revenues On Doc

So I've been having fun keeping an eye out for revs on docs recently, and have picked up a total of 5 docs from one seller on eBay recently. Just in was an 1871 NY Mortgage deed with an R27, R67 and R81. Tricky identifying silks on doc and the R67 particularly so. Pretty sure the R81 is silk based on a thread, ink color and thickness of paper. Whats interesting are all the plate scratches (if that's indeed what they all are) the biggest of which I've circled. Are there particular positions on the plate more susceptible to plate scratches? Maybe towards the edges? I would imagine this is quite common on later printings. The R27 has a nice embossed seal and is on a smaller attached piece of pink paper. Just thought I'd sow-and-tell.
Happy hunting!

I have been attempting to plate R67 ,late state, solely by the scratches. This project is 90% complete and when completed will prove to be the easiest plating to recreate. So far every position has identifying scratches, some very prominent. I don't have a R81 late state plating but a quick look at 100 or so copies show only a few positions with clear scratches. I know who has completed R81 and R82 and will check with him for a better answer. I have no idea what they did to the R67 plate but it's a mess! Karl

Hi southpaw, beautiful revenues!

This year I have been fortunate to pick up several lots of US revenues and other BOB.
I love the intricate revenue graphics. Being new to revenues, I wonder if any publisher produces (or produced) a hingeless album for these US stamps? I currently have an old Scott Specialty 2-post album with revenue pages. The rest of my US collection is in hingeless albums with top-loading mounts (which I prefer). Now that I have several groups of BOB, including many revenue, plus some documentary, wine, spirits, proprietary, telegraph, and motor vehicle. Most of these stamps are either hinged on Scott pages or loose.

What's the most comprehensive album for US BOB?

The $2.00 conveyance scratch was written up by D.A. Woodworth,Jr. in ARA March-April 2006. This is a constant variety on the late state. Fellow plater, Dr. Steven Perch, advises me that half of the late state positions show significant scratches, although this position has not yet been locked in.Karl

Thanks for the info Karl! I've been meaning to join the ARA. I'll do so today.
