Unc. $1 1988A Ja Block

This is just an idea, and I don't have any knowledge to back it up, but is it possible this run was printed for 'foreign' use, perhaps in Liberia, which was dual currencied at that point in time? Or Panama, which has been dollarized since 1904. El Salvador and Ecuador went to the dollar in 2000 and 2001, as I recall, so they would be too late.

sounds like a typo to me. my book says $4.50

Thats called inflation, they just move the decimal point over by one every so often...

Zee,

I've always been understood a run to be any print order to produce any size order of a single product. It's the same basic concept as a first edition or second edition, etc. of a book.

The way I visualize it, it's like your local daily newspaper. That newspaper has a daily circulation of X copies. But, each day, it might have multiple editions. Each individual edition would be a 'run'.

A low run just means fewer examples are printed. For example, an emergency issue of a currency.

Normally, I'll agree, the distinction of a run is meaningless, unless there is an anomaly associated with that run. Emergency issue, an error specific to a run, or something of that magnitude.

Sometimes it gets rather silly. I've seen Mexican provisional banknotes sold, where the seller seeks a premium based upon a low serial number, for example 07533. Well, a knowledgeable collector could easily determine that only 8400 bills were printed, so 07533 is not, in fact, a low serial number.

Well... I'm going to lapse into my 'opinion' here. I wouldn't consider the $5 FRN to be a low S/N, personally. If 520K bills were printed, I would want to see a leading 0, and the A suffix. So, my definition of a low S/N would be F0999A or lower. Then again, I'm a bit more of a 'snob' in that regard than the average collector.

Now, you can find yourself in a situation with modern notes, where a small segment of an FRB's allocation is dedicated to a specific 'run'. For example, the defense department could call the BEP, and say "We need 4 pallets of $100 bills" in Iraq. Since that amount is actually large enough to print a run, the BEP could assign a special block of S/N's to the job. Then BEP could look at the number of bills ordered by the different FRB's, and say a certain district was a little low in their orders, they would assign that 'run' to that district. So, if Cleveland, hypothetically, wasn't ordering as many $100 bills as the other districts average, the bills would be assigned to Cleveland, and BEP would deliver 4 skids of $100 bills from the Cleveland district to the Dept. of Defense.

Another thing to consider is 'terminology.

A lot of people don't understand the process fully, and use the wrong terminology.

A series is just that. All items mandated to be released at one time, bearing certain distinguishing characteristics. For example, a series number, signatures, etc.

A job is the overall mandate to produce a theoretically unique subset under that series, for example "We project we're going to need 52,000,000 $100 bills in the Boston District during the lifespan of this series"

A run is the smallest subset. It's the actual items produced without changing any variables. To use a very simple example here, If I put a sheet of paper in a photocopy machine, and press 250 copies, my maximum 'run' will be 250 copies. But, if I run out of paper, or toner at 95 copies, I actually have two 'runs' in my 'job'.

So, in theory, a 'run' begins when you fill the ink drum, load the paper and mount the plates. Anytime one of those variables is altered for any reason, your 'run' is over.
