What do the terms par value, purchase price, call price, call date, and coupon rate mean in the context of bonds?
Unless stated otherwise, these terms apply to all bonds. The par value or face value of a bond refers to the value of the bond when it's redeemed at maturity. A bond with a par value of $10,000 simply means that if you purchase the bond and hold it until the maturity date specified in the contract, you receive $10,000.  The purchase price, however, is exactly that: it's what you paid for the bond. Bonds may sell below, at, or above par. Continuing the example from above, if you paid $9,800 for a bought a bond with a $10,000 par value, you bought the bond below par. A bond selling below par is said to be selling at a discount. For bonds selling above bar, they're selling at a premium. If the purchase price and the par value are the same, the bond is selling at par. These terms apply to callable bonds only, which are bond contracts that allow the issuer of the bond (in the case of municipal bonds, the institution or agency who created the contract) to buy back from bond holders at a given date (the call date) and at a given price (the call price) before the bond reaches maturity and pays the holder the full par value.  Yes, the coupon rate is essentially the interest paid. It's usually represented as a percent of the par value, so if the $10,000 in the example above had a 5% coupon rate, this means that it paid out 0.05 * 10,000 = $500 each year. Usually, this payment is made as two semi-annual payments of $250. Some bonds are zero-coupon bonds, which means exactly what you would think; they don't make any coupon payments. U.S. Treasury Bills are one example of a zero-coupon bond. All of these factors are linked, because the coupon rate, callable provisions, and par value, along with the overall economic environment, can affect the purchase price of a bond.
