1. It is a Harding stamp.
2. It is a flat-plate printing.
3. It is not appropriate to use one Bureau Issue (the Franklin stamp) to determine if a different Bureau Issue (the Harding stamp) is flat-plate or rotary press.

1. Yes

2. The flat plate stamps measure 19-1/4mm X 22-1/4mm. The rotary are 19-1/4mm X 22-1/2mm. I use a Precision US Specialty Multi-gauge but any finely graduated rule may work (with a magnifying glass if needed) or digital caliper can also come in handy,

3. No it's not generally done, at least I don't think so, I don't myself. But if the measurements in question are exactly the same I don't see why you couldn't....

My question is are these the 610 or 613 the website I posted the 610 page at the bottom said to cut all four corners of the Franklin stamp and you would be able to tell but I did post measurements pictures b4 on here about to send them to get certified but I want to be sure of what Harding stamps are they 610 or 613

The setoff on the back says flat plate. The odds against this block were tremendous anyway. Think lightning strike while hitting the lottery at the same time. Always assume you have the most common stamp to start with. No, there is no reason to certify this block.

Edit to add: Trying to measure designs by the mm is a fools errand.

Not once did anyone ask what the perfs were? If it was perf 11 it was a #610 and if it was perf 10 it was a #612. Rule #2 - determine the perfs. Rule #1 determine the design.

We know by looking at it, it's either #610 or #612 and perfs would tell you the answer other than quickly looking at the back to see if there was ink from a flat plate that would quickly mean it's a #610.

There's only some 45 known #613's in the WORLD....it's not these.

I did not have to ask. I can see from the scan the stamps are perf 11.

rogdcam is correct ... you can see from the scan that these stamps are perf 11 rather than perf 10. The great majority of the U.S. definitive stamp designs of the era (or pretty much any other era, for that matter) are 19-20 mm in width. Since the perf gauge is the number of perforations over a distance of 2cm (or 20mm), one only need count the number of perforations along a horizontal edge. Now if 10.5 had been an option, I probably wouldn't trust my ability to discern the gauge by counting ... but judging between 10 & 11 is easy.

Thanks everyone but some research indicated some 613 you will see some spots of ink from sinking through but not as much as the 610 flat would have do to the laying on top of one another before the ink could dry they definitely 11 perf

Please cite a source for this, thank you.

At some point no amount of information, insight and experience we can provide here will convince you that you have a 610, despite many decades of combined collecting knowledge by those who have replied to your thread. At that point we tend to give up and encourage you to waste your money and send it away for a certificate. And to report the results back to us. But why would you believe a certifying organization either when they contradict what you want to believe? Sigh.
