Hello!! Greetings to all of you. I've been keeping this coins for myself for god knows how long but today I'm gonna share it all to you just to give an awareness that this coins actually exist.
I don't really know if its a trial / test / experimental or pattern coin, I really don't want to speculate.
This are the details of each coin base on my many many years of research, please know that this is my hypothesis that I intended to share as a head start to those who want to know further about my coins.
Here are the details:
1. 1965 Proof Quarter
no mint mark2. 1969 Proof Quarter
no mint mark3. 1974 Proof Quarter
no mint mark4. 1979 Proof Quarter with D mint mark
5. 1985 Proof Quarter with P mint mark
6. 1986 Proof Quarter with P mint mark
7. 1988 Proof Quarter with D mint mark
8. 1990 Proof Quarter with D mint mark
9. 1991 Proof Quarter with D mint mark
10. 1991 Proof Quarter with P mint mark
11. 1993 Proof Quarter with P mint mark
12. 1983 Proof Dime with D mint mark
13. 1946 Proof Penny
no mint mark - even the 1946 "S" is a regular strike on this year.
14. 1960 Proof Penny with D mint mark - this is not a D over D but there is another D is on the rim.
15. 1967 Proof Penny
no mint mark - it has a diamond tipped pit in both 12 o clock position on obverse and reverse.
16. 1971 Proof Penny
no mint mark - 1971 "S" proof is rare and very expensive, what are the odds? you can do the math.
17. 1975 Proof Penny
no mint mark - it was struck/stamp by something by something that I don't know, its far from the date though.
18. 1979 Proof Penny
no mint mark19. 1953 with D and 1973 with D penny - this two are actually also proofs but I experimented on them a long time ago, I left them in the open and change its location every 2 weeks to a month. different humidity, temperature etc. but not in the elements like sunlight or rain. and as you can see they tarnish differently. one has a light brown and the other has a beautiful orange red tarnish. it seems that all of this pennies have different metal composition.
20. 1989 Proof
Jefferson nickel with D mint mark
21. "1963 Proof Jefferson 90% silver with
no mint mark" - First thing you will notice about this is its more white, it really stands out to the other nickels. Its a little bit small in diameter, and thinner. Its about 20% smaller in total compared to a regular nickel, but its weight is 4.8 grams, it doesn't make sense for it size. So its suppose to weight only 4 grams for its size, its 0.8 grams denser then. Next I did was an ice cube test along with a normal 90% silver coin, a 40% silver coin and a normal nickel. I did it many time and I get same result, its as fast or sometime 2-3 seconds slower than 90% but that was understandable because I use a 90% quarter as a comparison, its has a larger surface than a nickel. I haven't tried any other test aside from that not only because its valuable but its my most favorite coin among all them.
If you guys have more questions or some test you want me to perform on this coin, if its possible for me and it won't give any damage to the coins please fell free to ask. Anyway thank you for letting me join this forum. Have a nice day.
