I would love to give you advice you could take to the golden bank, ... buuuut my crystal ball is in the shop!
I understand you want to aquire gold, so do I, but to sell your silver for it.... now?
Frankly, I am too ignorant to give you advise on that. I will let others make that call.
The last big dip in 2008 was not that great a deal in my home town. Dealers said they had no silver or gold to sell. That was only partially true. They really meant they had no PM's for sale at the then current spot price. They were holding out for the price to go back up. It's "funny" how the spot price is so very important to them when it is rising, but meaningless when it goes down. The point I am trying to make is if you sell your silver today... who is going to sell silver back to you tomorrow??? If you are confident you can buy back silver at a lower price in the future... then, let your conscience be your guide.
Allow me to offer some alternatives to selling your silver:
Got a real fancy ride? Sell it and buy a real cheap car... buy gold with the difference. You can buy a better car later.
Got a fancy boat? Sell it. Boats will be dirt cheap when unemployment hits 25%. Buy gold.
Is you house paid for? Do you have an adjustible rate on the mortgage? Deal with that, too.
Do you have any unwanted real estate? Sell now. Buy gold.
Is there any other fancy do-dads you have that you could sell today, buy gold, and then buy another do-dad a few years from now with your au/ag profits?
You get the picture.
If you want to get completely out of silver and permantly into gold. Oh yeah, sell, sell, sell!

When I die, I want to go like Grandpa did. He died in his sleep..... Not screaming and hollering like all the passengers in his car.
