These are some of my best Currency errors..
First is a cutting error that had taken 2 submissions and 6 months for PMG to understand that this was a genuine error, and not one of the many fakes that
ebay allows on their site..
This frosted me as I included all the necessary information on the PMG form showing the error to be genuine, only to learn that the PMG Graders have zero access to the submission forms, and information is NOT shared..

Next is my PMG Natick and Web errors that had been in individual holders till a few weeks ago when I had them placed in chronological order, in a 3 - Note Holder..
Since these are the only 3 $1. FRN Blocks that can be classified as overprint on back errors on Experiemental Notes, and the 14 year long search to obtain one example each, I believe it belongs together as a complete set in one holder..
This set is followed by 2 more Natick Errors, one PMG & the other PCGS (they would make the correction as PMG did, but I don't have a PCGS acct.)

Later experimental runs were not always so easily detected. One print run of Series 1963 $1 FRNs was produced on experimental paper, but it was not identified by either special serial numbers or distinctive markings. In this case, the BEP's purpose was not to test a different paper composition, but to test the ability of a new supplier, the Gilbert Paper Company, to duplicate the usual currency paper. The notes involved in this test were numbered C 608 00001 A through C 614 40000 A. No additional paper was ordered from the Gilbert Co., but the option was left available in case the BEP's usual supply of paper was ever interrupted.
A similar experiment took place in 1981, when the BEP produced a few print runs of notes on Natick security paper. The notes involved were Series 1977A $1's with serial numbers E 768 00001 H through E 806 40000 H and E 070 52001 * through E 076 80000 *. (Note that many references incorrectly list this star range as Philadelphia instead of Richmond.) One run of $10 star notes was also included in this paper test, making it the only experimental printing so far not restricted to the $1 denomination.
A more recent example of an experiment involving $1 notes was the trial use of a web-fed printing press in the mid-1990s. Unlike the earlier experiments, in this case it was the printing technique and not the paper that was changed. Also, the number of experimental notes released for circulation was much larger than in the previous instances, as tests continued over a period of several years. For some background on the web press, and a table of the serial number ranges of the notes printed on it, see the page on web notes.



Anyone following my Natick and Web-Press Error Census here on CCF, knows the Confirmed Natick Error Test Notes is currently 14 Notes (from a span of 18 16-subject sheets) and 5 Notes Each from both the series 1988A Web A-F & G-P Blocks. While many Natick Errors await discovery, only the right half of one sheet each has the overprint on back error..
These are the only 2 Half Sheets with this error in the 4 1/2 Year Web-Press Run..
Should anyone have a Inverted Overprint on a Web-Press Note, post it here as they are extremely rare also..
Next is a unique bank of England 20 Pound triple serial number error I purchased from the person that received it early March 2006.




In the 10 Year Search since this error was found, no other notes from the 40 subject sheet have been located, and I have spent countless time searching and subscribing to Token magazine, to post this note in their magazine..
Next are 2 Pakistan double serial number errors on 2006 dated 1000 Rupees (1st released in circulation on Feb.26,2007)..
I purchased these in 2007, and with the wide spread of serial numbers, had held off on certification until mailing them out today to PMG..
To my surprise, I have found no other examples in the 8+ Years..
Also unique (IMO) is the multiple prefix letter, 1st I have viewed..
With my past history at PMG, I included 8 pages of this notes security features information attached to both notes for the graders (if they have any trouble confirming these, they need to seek other employment)..
When I receive them back, I will post what this note looks like under a black light (awesome thread colors)..

That's it for now, and most likely forever..
