Re: .05% &.01%
Not only did I look for wheats, but I noted how often each Memorial date showed. I never did complete a whole Memorial set from just $10 (came within three dates a couple of times).
From 1/14/96-10/5/96 here's what I found from searching 100,000 pennies -
396 wheats (averaging about 4 per $10)
- 235 from 1950-58 (most common 1958D - 39)
- 132 from 1940-49 (most common 1945 - 15)
- 13 from 1930-39 (most common 1936 - 3)
- 6 from 1920-29
- 9 pre-1920
- 1 dateless
- Found all from 1941-1958 except: 1943PDS, 1952, 1954
- Pre-1941: 1940PS, 1939PS, 1938PD, 1937, 1936, 1935PD, 1930PS, 1928, 1926, 1925, 1921, 1920, 1919PS, 1917PS, 1916, 1914
218 Canadian (averaging two per $10)
- All dates from 1962-present (most common 1981 - 15)
- Pre-1962: 1957, 1956, 1951, 1940
Foreign
- Panama 1 centesimi - 1968, 1975, 1978, 1987
- Jamaica 5 cents 1969
Miscellaneous
- 1898 Indian (woo hoo!)
- 1990S impaired proof
- a cent-sized Denver Mint insert coin
Odd Facts
- 1958D was more common than 1959, 1960, 1962 or 1963
- 1956D was more common than 1960 or 1962
- Wheats: 50% of all dates found; 25% of pre-1940
- Found two 1917S's but no 1952 or 1954
- Least common Memorial 1960 & 1962 - 31% of the time
- Canadian: 84% of Queen Elizabeth series found
Interesting to note that only three times did I find no wheats out of a $10 batch. The most was 10.
I just went thru $10 worth a few days ago and it was so much work I don't know how I did it 100x back then!
