2024 Auction Will be Held September 21-22


Cedar Valley Rocks & Minerals Society holds an annual 1- or 2-day consignment auction in September.

The 2024 Auction will be held Saturday and Sunday, Sep 21-22.
  • The 2025 Auction will be held Saturday and Sunday, Sep 20-21.
  • The purpose of the auction is to help collectors or families of collectors dispose of their collections.

    Knowledgeable club members act as auctioneers. Since the auctioneers are also collectors, they bid openly on material that interests them. Auctions typically attract about 100 bidders and are limited to 800 lots for a 1-day auction and 1200 lots for a 2-day auction. Viewing is from 5:00-7:30 Friday night, at 7:30 Saturday morning and 8:00 Sunday morning. The 1st day runs from 9:00 a.m. to about 8:00 p.m. with hot food available during the day and a dinner offered from 5:30 to 6:00 p.m. The 2nd day runs from 9:00 a.m. to about 3:30 p.m., again with hot food available.

    Cash, credit card (with small service fee) or good check is accepted for payment. Iowa sales tax of 7% is also added to all items. Bidders who provide Iowa tax permits are exempt from paying it.

    If you can't stay for those special lots you want, you can leave a maximum bid, and a club member will bid for you up to your maximum.

    Motel rooms are available in Amana, but they are sometimes sold out. Motels are also available in Little Amana (15 minutes away), Cedar Rapids & Iowa City (each about 25 minutes away, although motel rooms are scarce in Iowa City on home football weekends).

    Since each sale has several consigners, the sale rotates among the consigners. All lots are numbered, and an order of sale is available at viewing on Saturday morning. Equipment sells at 2:00 on Saturday.

    If you have a collection to dispose of, please contact Marv or Sharon. The club does all the advertising and sets up the Friday before the auction. A 25% commission is charged for non-members, and 20% is charged for members or families of members who have belonged to the club for at least 2 years.
