Silver bars and rounds are good liquid investments as they hold their value quite well and can be bought and sold at prices close to their spot or market price. I collect them and hold most in my safety deposit box and during my last visit to my box I grabbed this cool one ounce silver bar from the refiner Sunshine Minting who makes bars in one, five, ten, and a hundred ounce bars. Below are pictures of this one ounce silver bar which actually has a security feature on the back of the bar whereby with the use of a Sunshine Mint Decoder Lens can verify the authenticity of the bar. When viewed with the decoder the circle on the back of the bar will read 'Valid' and when turned to 90 degrees a sunburst will appear for those bars that are authentic. I find silver bars like this to be very liquid as I can go to numerous bullion dealers and I am able to buy and sell them for prices within 5% of their spot price. Over the long term their value will likely appreciate by around 3% thereby keeping up with inflation. The one ounce silver bar below is worth around $16 US or $20 Canadian.
