red red gold gold gold (yes, three golds)
What is its value?
Thank you

Have you thought of measuring its resistance and then deciphering
whether the marking has any relevance or it is simply incorrect
banding?

Bet it's 2.2R :^)

If it was not broken......

5. ### SlangGuest

Thank you, me too but there is too much gold .... (i have only seen two
golds till now)

It's 0.22 ohms, 5%. The first Gold shifts it one decimal place, for
2.2, the second Gold shifts it another decimal place, and the third is
the tolerance.

7. ### SofieGuest

The third band would be silver if it is really a 0.22 ohm value.
My money is on the value of 2.2 ohms.

A highly relevant piece of information which you omitted from your
initial post.....
Sometimes it is possible to remove the paint from the broken ends and
gain access to the resistive spiral (assuming a ceramic body) so that
you can measure each part. I have done this myself.

Thank you so much, that was the right way!!!!
2.2 ohms it's the value

Presume .22ohm probably 1/4 - 1/2 watt @ 5% tolerance, measurement will
clear up all doubts if you are able to read the initial value of the
original.

I seem to recall reading somewhere that the 5th band (rarely used/seen) had
to do something with long term reliability.

This should be a 2.2 ohm 5% precision resistor given the gold multiplier and
tolerance bands.
