I expect to be able to buy full sets for $12.50 or possibly even less when people consign them to absolute auctions. There will be so many sets around that they will not bring a significant premium for a century, unless one of series has a very small mintage for some reason. If your coins came out of circulation, they will not have any added value, and probably never will. This is because there are so many people making sets from coins in uncirculated condition -- nobody will want a circulated set when an uncirculated set is so easily available for so little of a price. There are hundreds of millions of each state / each mint produced. It's not likely any of them will ever be considered rare or valuable. If you're making a state quarter set, don't do it for any investment potential, do it for the enjoyment of getting all the coins together and having them all.

Fairly cheap depending on what you are looking for. Best Buy has several under one hundred dollars.
It depends on the condition and mileage. If its in a fairly good condition with mileage around 150K, CAD5000 - 6000 would be a resonable range for it
The Cal Ripken Jr. Highland Mint Bronze collection is fairly valuable. Collectors will buy this item for between $100 and $200 each.
About $1,250 for Excellent condition. Fairly pricy guns
Depends on condition, condition, and condition. Anywhere from a patina shooter at $200 bucks to $1200 new in the box. They don't typically get over $500 until you have some fairly good 85%+ overall condition.
Slaves were usually responsible for keeping their own living quarters clean. So it differed, but in most cases the answer would be 'fairly regularly'.
No mint marking
If it was bought as part of one of those "rapidly vanishing US coins" collections sold in the backs of magazines, it's worth less than what you paid for it. These coins are usually average condition and carry a fairly stiff markup. Please see the Related Question for more information.
It stands for "Very Good" and is a numismatic term of art describing the condition of a coin. Confusingly enough, "Very Good" condition is what most people would think of as fairly worn down.
