Should It Be Illegal To Sale A US Postage Hand Stamper?

Should it be illegal to sale a U.S. Postage Hand Stamper?
I got to looking at forgy online with postage and they sale all over the world these Postage cancel hand stamps . Different times of the century. There for sale in Europe mostly. A lot on ebay also. I looked at completed sales and a lot sold in the United States. Im scared to buy now off anyone on ebay. I really get my stuff from fle hops and yard sales. This is really ruining my day. What stops them from making these covers and faking the cancels with original U.S. Cancels?

Yes this happens in europe too.
But to make a forgery you need the right ink too. Maybe the problem is not so big for a specialist.
We need to learn and to study the ink types that were used in the past.

I don't like it...I'm a really big skeptical now. Ill stick to my yard sales I guess.

The only thing I could do, when I heard the first time of this was to get certificates for my expensive stamps.
But my expensive stamps come from auctions and they have printed catalogues.
So I can prove that cancels were on the stamps before the stampers came on the market, I believe they came the first time on the market 10-15 years ago, that was at an auction in Germany.
Most old stamps are mint more expensive than used. So that reduces the problem too.

But there will be a risk for investments.
Auctions are good in my opinion.

I once bought a stamp, for example the cat.value was 100.00 ( incl. the expensive cancel) I wanted it because it was with a cancel of the village where I was born, so my bid was 200.00
Next year the cat.value of the stamp with this cancel was 400.00!
If I had bought the stamp in private, the price would be still 100.00
So info on paper, a bill, a catalogue of the auction, or a cetificate can proof that a stamp and cancel is genuine.
We Always have keep our eyes open! Things change.

Faked cancellations have been around since the 1800s. And while making used legitimate devices illegal in the after-market sounds good, we have to remember that people have been manufacturing cancellation devices and perforators meant to deceive for over a hundred years.

By the way , for as far as I know... the first postmark was Dutch, the first stamp was British.
Maybe the first fake postmark was Dutch too.
The VOC used postmarks on post from the dutch (west)EDIT: EAST indies to the Netherlands.
