Hi Mike,
Ah well, maybe it's too early to have a real physical catalog that bundles and discribes all probe's ?
I'm pretty sure someone, in the future somewhere, will get buzzy on it.
I also update photo's if the quality isn't sufficient or when data is missing.
Bought myself a digital scale (0.01gr) & digital caliper (0.01mm) only to get the data from some of my coins and place it here online...
I wanted to add all 9-coin luxe-box sets of Euro Probes i have but am having difficulties getting them thru the authorization 100% !!
Like this one:
1 Cent - Malta 2004 (9 coin box-set)
You can see I've upgraded pictures into 1200dpi scans, I've added all measurements and added other coins on the page from the serie.
All pages got authorized except the 5 Euro... For some reason that I don't understand...
If someone could give it another go maybe with more luck ?
5 Euro - Malta 2004 (9 coin box-set)
Here's all data needed:

You can see the 5 Euro actually is Gold plated, not Copper-Nickel !
Weight: 25.51 g
Size: 36 mm
Thickness: 3.34 mm

See Also: Add other 8 coins from set (1 Cent > 2 Euro)
Date: 2004
Mintage: 3500 (Comment: 9 coin Box-Set)
I think I covered all needed... I hope someone has more luck than I had !
Cheers,
doc
