The radiant time series (RTS) method is a new method, derived directly fiom the heat balance method, for performing. design cooling load calculations. It effectively replaces all other. simplified (non-heat-balance) methods such as the cooling load.
The last wheat pennies were made in 1958. They were produced from 1909 to 1958. They are generally common and worth a few cents above face value and can be found in pocket chaâ¦nge.
As all 1944 pennies were wheat. However, if your penny is steel you have a very nice piece of histoâ¦ry. In 1943 all pennies were steel because of the lack of copper in WW11. But, in 1944 there were some 'error' pennies that were made of steel instead of copper.
