💵 Coin Collection Value Tracker
Add each coin's estimated or catalog value to see your collection's total and average value per coin.
What the two figures are
Every row you add contributes one value, and the card at the bottom reports the sum and the plain mean:
total = value 1 + value 2 + ... + value n
average = total / number of rowsThe three rows on load are a Morgan dollar at $40, a wheat cent lot at $15 and a foreign set at $25, giving a total of $80 across three rows and an average of $26.67. Add Coin appends a row at $10 that you overwrite; a blank or non-numeric value counts as $0 but still counts as a row, so it pulls the average down.
Choosing the number you type in
A coin has several defensible values and they are far apart. Pick one and use it for the whole list, or the total means nothing:
- Catalog or guide value - the Red Book style retail figure. Fine for insurance replacement cost, high for anything else.
- Realized prices - what comparable examples in the same grade actually sold for at auction or in completed listings. The honest middle.
- Dealer buy price - what you would be handed today. Expect well under catalog on common material, and near melt on bullion-grade silver.
Frequently asked questions
What value should I put on my coins?
Match it to the purpose. For an insurance schedule use retail replacement, for a sale use recent realized prices for the same date, mintmark and grade, and for a quick cash figure use what a dealer would pay, which is lower again.
Why is the average per coin so misleading?
A mean follows the largest number. One $500 key date beside nine $5 coins gives a $545 total and a $54.50 average, which describes none of the ten coins. Read the average only when the rows are roughly comparable.
Does the tracker save my collection between visits?
No. There is no account, no storage and nothing sent anywhere - your list exists only while the page is open, which also means nobody else can see it.
