The second comma (at the end of the title) leads me to list other units for this temperature:

(most interesting perhaps) Kelvin = 511
919.8 degrees Rankine
190.3 degrees Reaumur

Perhaps these indicate (somehow) an order to the items displayed in the image?

This is the first silver i've got so i'm quite keen to solve it.

The small words all over the card say the following:

Smite
Deal
Edgy Name
Io
Ken Ana
Data Sear
Cream
Lama Heat
Pisa Heap
Hail Aim
Last Coil
Ponies
Aero Up
Hasty Lie
A Lear
Be The

they are repeated all over the card in no obvious pattern although they do appear in lines vertically and horizontally.

There are also the numbers 1 to 16 dotted around the card.

Could you maybe list what the little letters state? To give us an idea on what we should be speculating about?

I don't think you could heat the card up that much, isn't F 451 the combustion point of paper (hence the title of Farenheit 451)?

[BBuck]

Or could the temperatures in the title refer to the boiling/melting/freezing point of a substance? Are the other things on the rest of the card temperatures plotted on a graph?

[Curlytek]

So, given the title, should this card be heated up (pretty hot it must be said!) to reveal something???
