in response to your question about pennies being removed from circulation affecting market demand and prices...
Items that appreciate are usually varieties that are found (a number in the date that has been punched twice or other random features), or low Mintage dates (where many fewer coins were produced relative to neighbouring years).
Take for example the last year 2012 pennies
Everybody who was into collecting coins or not perceived that it might be worth something in the future and probably set aside a bunch of them.
Not to mention that the mint sold the last 20,000 rolls with serial numbers printed on them. - if I remember correctly the first and last of those 20,000 rolls of pennies sold for $5000-20000 .... 50cents in face value for a roll.
It's always a toss up and hard to predict the future of what will appreciate
