Antiques

A friend found a bounty of old coins, mostly from the 30's. Most are weathered, dirty, etc (however the one paper $ found-a1957 Silver Certificate-is in great shape). We need a crash course in how to care for them and what potential value they have. Thanks!!

Me and my dad have got a good collection of antique coins from India. Its from 1900-1975, majority from British Medieval time.

I want to find a place in U.K or U.S where i can get to know actual cost of these coins or if i can put them on auction or can sell them straight away at good price. Please help me out. Its kind of serious as we got some financial crisis.
