You really need to educate yourself about the coins you have. There is a very true saying in coin collecting circles, "Before you buy the coin buy the book." Basically meaning before you start collecting any particular coin series read about that series. In you case I say, Before you sell the coin buy the book.
You need to get knowledgeable as to what you have, what condition the coins are in and what the possible "Key dates" you may have.
You can get a lot of information at the library and on-line.
You could sell them on
ebay, but be careful of fees eating into your profits. Follow these rules to cutting down on your fees.
1) Use all of the 50 free listing you get a month
2) Don't wast money of "listing features" or unless really necessary, subtitles.
3) List the item for the bare minimum price you will accept for the coin, if the coin doesn't generate many bids you won't be that disappointed.
4) Watch your email for the one or two promotional periods
ebay has every month when you are permitted thousands of free listings during a short period of 3 day to a week. They will be either auction or fixed price. These listings are in addition to the 50 free listings you get every month. These periods are often near the end of the month, if you haven't used all of you 50 free monthly listings you can list those in the alternate manner than the promotion. So if
ebay is giving you 10,000 free Fixed Price listings, you can still use the 50 free monthly listings for auctions.
5) If you going to sell a lot of coins consider opening a store since Stores are now charged 6% Final Value Fees on coins as opposed to 10% for non-store listings, just make sure you're selling enough since the basic monthly store fee is $19.95.
6) Lower value coins rarely sell because the shipping charges are more than the coin is worth. you need to bunch them up. I break open many Mint and Proof Sets and make full year sets of coins for all denominations and sell them like that. Each year set includes coins from all the mints, So for
US coins there are the Philadelphia and Denver issues of business or Satin Finish strikes which I match-up wit the corresponding Proof coin from the San Francisco Mint.
I've been selling coins on
ebay for years and following these tips I NEVER pay a listing fee anymore. One thing to keep in mind is to be ready for those brief free listing periods by taking pictures of all your coins and drafting the listings beforehand.
ebay give short to no notice prior to the promo period so being prepared enables ypu to get in as many listings as possible quickly.
You can also open a free store at Bidstart.com, They also give you 50 free auction listings a month, addition listing after that are only
Two Cents. But all fixed=price listings are free with a basic store. Their final value fee is 9%, unlike
ebay, BidStart doesn't charge a final value fee on shipping charges.
Good-luck!
