Checking out something in a basic numismatic reference book is old habit to most collectors. Sometimes we are just curious, but more often than not, the information we are looking for is a necessity.
Sometimes, though, we allow the copies of the references we use to age beyond a reasonable point.
Prices are out of date. New issues might be missing.
If you are feeling the need to replace one or more of your basic references, now is a good time to do it.
ShopNumisMaster is having an online book sale now through Monday with 40 percent taken off the price.
See for yourself. Then enjoy your weekend.
