First build a time machine to travel back to the early 1960s. Then go to a bank with a silver certificate and ask the teller to exchange it for silver coinage.

One dollar is the same as any other dollar. As opposed to silver dollars being worth more than paper dollars.
Most banks have a coin sorter where you can exchange them for cash. Another option is to roll them into paper wrappers. For pennies you should have 50 cents per roll. Banks will usually take them, but ask if there is a coin counter first and bring them in loose if they do have a coin counter.
It's almost never a wise idea to cash in old paper currency. Banks are not permitted to buy collectible money; they can only exchange it for current coins or bills at face value. All you'd get would be a nice 21st century $1 bill or $1 coin. However depending on its condition and series letter, a 1928 US 1 dollar silver certificate can be worth anywhere from a few dollars to over $1000 to a collector so it should be evaluated by a dealer or appraiser. Please see the question "What is the value of a 1928 US 1 dollar silver certificate?" for more information.

The value of a paper bolívar from the Banco Central de Venezuela can vary significantly due to hyperinflation and the economic situation in Venezuela. As of now, the exchange rate fluctuates, but one bolívar is often worth only a fraction of a cent in US dollars. For an accurate and current valuation, it's best to check a reliable financial news source or currency converter.

These bills are normally called silver certificates rather than "paper silver dollars". A date is needed to give a value - please check the date on the bill and post a new question "What is the value of a (date) US 1 dollar silver certificate?" for a specific answer. Up till the mid-1960s it was possible to exchange silver certificates for $1 in silver metal, but that practice ended when the price of silver was deregulated.

The official exchange of Deutsche marks has come to an end. However, you can still take your old German currency to the Bundesbank (Germany's Central Bank) and exchange it for euros. Most currency exchanges (banks, airport exchanges, etc.) will only buy currency that is still in general circulation. Specialized currency exchanges such as Euro Coin Exchange (http://www.webuyeuros.com/germany) will buy your old marks, and you can get paid in dollars without having to ship your cash to Europe.
A silver certificate is paper currency. It is not a coin. No silver dollars were minted in 1943, and no silver certificates were printed with that date either.
