If I decided to try crowd funding this I would only really be looking at a decent printer, and 1st batch of customer stickers i think. Decent stock paper is another story...
Still not sure if this project even has enough traction yet.

Decided to make an ebay posting: http://www.ebay.com/itm/271185863718

Update: Ebay took the original down, and kind of apologized, but... http://www.ebay.com/itm/271187225118

I have ran into a bit of an issue where some of my transactions are not getting firstbits assigned to the addresses, this causes a problem.
Not sure how to combat this yet.

[Update: Seems like this has been resolved.]

Im not sure if it was the case or not, but I now have an SSL cert setup and working for anyone that was nervous about purchasing from my site for security reasons.

I am real, my checks are real, and my (so far) happy customers are real.

Just as reminder, email addresses on orders are only used in the event of a problem with your order where additional contact is needed.

so it might make it to the bank without being properly redeemed if it was just one in the big pile of checks.

Kind of like the catalyst to what got Liberty Dollar (Bernard von Nothaus) shut down, ... when the bank got one as a deposit?

These are missing most every requirement of a cheque (or "check" in the U.S.).

 - Drawer (the person or entity who makes the cheque)
 - Payee (the recipient of the money)
 - Drawee (the bank or other financial institution where the cheque can be presented for payment)
 - Date

The check does have one of the fields:
 - Amount (the currency amount)

 - http://www.law.cornell.edu/ucc/3/article3.htm#Check

But it wouldn't hurt to be explicit - "not a bank check" or something like that.

Here's someone that created a fake check that had an ABA number (invalid) distributed to people with the intention, apparently, of deceiving the recipient into thinking it coiuld be redeemed for USDs.

Regarding these 'checks', there may be legal definitions surrounding the term 'check' such as implying it uses a bank clearinghouse, and that the 'check' can be stopped, which of course bitcoin can't be stopped. Maybe call it a voucher instead?

Also, if the check is the same size shape and looks like a bank check, it will be going into a cash register and being processed like the other checks - so it might make it to the bank without being properly redeemed if it was just one in the big pile of checks.

And, maybe some 'instructions' for newbies on the back? Maybe a statement "DO NOT send to your bank" in small print somewhere on the check?

Imagine if this was ramped up to be a major solution, companies would want to automate the removal of the private key holograms and scan the qr codes all with a machine of some sort.

Since I know my new revision will be under heavy pressure I am giving away more checks for people to test and destroy. 20 free checks will go out randomly. How do you get one?

I didn't feel the additional scratch off was secure enough nor could I really justify the cost just for an additional sticker, so I changed the checks in an attempt to crush some of that. Currently the private keys are printed in a light  grey color, but instead on a sticker I have a black bar with a watermark of sorts. Also while cutting materials, cutting the price to 75 cents seemed like a good idea too. =)

Sorry I was afk for so long, work has been crazy.

I did get a set of replacement checks and while I don't have any pictures I can say that simply putting an extra holographic sticker on the back absolutely solved the flashlight attack and I haven't found a way to break the new checks yet.

Here is a very nice review! Also, if there are any revision 1 checks still out there, I will replace them.

cheque was in the mail today. looks okay, but I probabyl wouldn't accept one for larger sums. the check itself seems still too easy to fake, the sticker can be bought by everyone, and I don't see the "artificial watermark" on the back. The only thing (besides the second sticker) that could be meant by it are some white letters on a grey background.
final verdict: would accept one for up to 20 fiat from a normal looking stranger.

from here https://bitcointalksearch.org/topic/1-year-anniversary-of-ibb-free-physical-bitcoin-cheques-89723
So the question is, How do I distinguish/protect against counterfeits...
You can't, which is why Bitcoin checks should only be used between trusting parties, just like regular checks.  Stores won't accept a regular check without seeing your driver's license (most of the time), and I imagine it would be a similar requirement for Bitcoin checks, if they were to ever accept them.
I agree that you can't make a check impossible to copy, but adding security measures would still increase the trustworthiness of a check and make it useable for larger sums. I understand if you don’t want to invest the money to get custom stickers or something similar, but as I’m skeptical if the niche you seem to be in will be profitable, since I see only two use cases at the moment.
1: people that know and somehow trust each other, but not enough that a handshake is considered enough.
2: strangers that want to exchange goods in person without having to hang around waiting for confirmations. This case has the problem that the check is imho only suitable for smallish sums and is relatively expensive at 0.25 btc. If the problem is the money, get an offer from a custom security sticker maker and crowdsource the costs. You can pay you creditors back with a bundle of checks and 10% rebate off all future offers.
