I have recorded all my coins on an excell spreadsheet with further ID in the trays.My wife and kids know a few of the dates...1717 dump issue,1698 etc.If I pop my cloggs the girls have enough wit about them to sell on.I did a collection of 1d's for both girls and they know what a KN/H & ME is although an open 3 1903 is in doubt.The gold,silver and hammered are clearly detailed but my 1859 1/4d's with or withour shamrock attached are more difficult...a close TT 1915 would be beyond them. I bought a R/E 1856 farthing from a dealer for a few £ he didn't know what it was and a large date/small date 1875....obviously a "dead" collectors spoils. My eldest daughter helps me sell on Ebay and I do the description...she is learning. She can look in Spink or CCGB and have a rough idea.I tell my wife and kids rather than pee it all up the wall I buy coins(I do like a pee aswell )Just do a good job in cataloging.
