There are a number of online stores that sell proof sets. The web domains "LittleTonCoin" and "GoldenEagleCoin," for example, are known to sell these sets.
Depending on what condition it is in, most proof sets sell for around $55.00. Some I have seen sell for $28.00 in mint condition. I own all proof sets from 1999-2009 and i can sell them all for around $609.00.
About $5-6 or so. Proof sets really have little demand anymore and so they are quite hard to sell in todays marketplace, aside from proof sets containing silver (yours has no silver though)
To begin with, there are Mint sets and Proof sets, and they're 2 different things. You'll need to check your set to determine which kind you have. Mint sets are sets of uncirculated coins selected from normal strikes. These retail for about $15 to $20. Proof sets are specially-struck coins that have mirrorlike surfaces and matte-finish images. 1995 proof sets sell at a fairly decent premium - cupronickel sets retail for $35 to $45, and silver sets are in the $80 to $90 range.
The 1976 proof sets sell in the $8 range. The Ike proof dollar by itself would be around $4.
British decimal proof sets in the early years contained few coins and were widely collected, they sell for about $10 online.
Where ever you want to. But a coin fair may be best if you want a good price or use eBay and set the reserve to what the set is worth.
No they do not, neither do 1984 Proof sets. The COA's for Proof Sets start in 1986.
No silver Proof sets were issued in the years given in this question. Proof Prestige sets were issued in 1986-1990 that have current retail values of $36.00. The standard proof sets are $6.00 each.
Around $8-13 or so. Modern non-silver proof sets are not in much demand and don't sell for much and coin dealers have trouble getting rid of them.
1,247,952 sets were made.
The current year Presidential Silver Dollar Proof Sets sell for between $75 and $100 on Ebay. They can also be had at local collectible shops.
