As saying goes this way:

my guess is that gold is more precious than silver thats why. greetings. : )

coz gold is even more precious

All of you know that "All that glitters is not Gold". Like wise the time is also not glittered but changes every minute with more glaze and colour, thats why it is called as 'Time is Gold'.

Gold is (or was) the most precious metal. Silence is also 'golden' but clouds tend to have a 'silver lining' ... odd, isn't it? I think people would tend to smile if one described time as platinum or iridium, though! In Yorkshire there is a saying 'Where there's muck there's brass' meaning that there's a lot of money to be made from the dirtiest jobs!

becuse it is more costly .......that is why it is compare with gold because gold is more costly than silver

Gold is more expensive?

Hi,when the proverb was framed the only valueble good was GOLD[no PLATINUM..NO DIAMONDS..]at the same time to tell the importance of the TIME,our elders compared with gold..

coz it is more precious!!

maybe cause is gold!
