Hi Pat,

Firstly I'd say that the bottom LHS chip doesn't count in the equation as it's an LCV, so different to the other three already, before you start considering UV's.

I would agree with Jim in that the top 2 are too close to be variations. There are a lot of chips that have slight shifts in the UV (see the Bellagio $1's which have too many to count) and in my opinion these subtle changes do not make a variation. (now that's just my opinion & how I collect UV's). Greg also told me the same thing when I asked him in regards to UV variations, and I use it as a rough guide with a little bit of common sense decision making thrown in.

But in saying that a UV stamp in the same position on the chip, with the same directional orientation can still be a variation. There seem to be 5 or maybe even 6 H&C UV's that were used. Different types & sizes, SCV, LCV, large, medium & small. So if the H&C is different, even though it may be in the same spot then I would call it a varation.

H&C UV Examples:

Also another but......Your chip on the top LHS compared to CG04373 on The Chip Guide is quite different IMO. There's a definate placement difference compared to that chip. And bottom RHS is not shown on The Chip Guide at all so that's definately a variation.

So, so far there appears to be.....

CG16798 - SCV Blank (no UV)
CG04373 - SCV large H&C UV
unlisted - SCV large H&C UV (Pat's chip, different UV location)
unlisted - SCV small H&C UV (Pat's chip)
CG16797 - LCV small H&C UV

Now, just to throw in some more, here are a couple I have in my collection. I'm not sure where the first one fits in or if it's a different H&C size/type to yours Pat but here it is anyway. It's always a little hard to tell unless you have them side by side under the UV light.

The second UV is a little odd in that it has a different H&C (large LCV) but also has UV ink behind the $1 & the location text.

Now....and this is where you brain starts to hurt.....there are variations in the chips themselves for Fitzgeralds $1's. The two below have very different printing on the inlays. So, you then have the possibility of doubling all the variations based on the initial chip variation (before UV's are taken into account). Brain hurt yet?!

The great thing about collecting UV's is you really don't mind if you get some duplicates in purchases you make because there's always the chance you may find another UV variation amongst the lot.

Happy chipping!!

Cheers, Tim.
