1971 Barn Owls - Franklin Mint, Roberts buy Bird Medals, No. 25: Barn Owls (Sterling Silver Proof) with Case & Display Stand

Roberts Birds (named after famous buy sculptor Gilroy Roberts) was one of the Franklin Mint's most popular issues, and also most unusual.

The medals were issued one at a time, rather than in sets, although each Series of 5 was priced at a discount.

Ten series of 5 medals were issued, called Series I through X (Series I is medals 1-5, Series II is medals 6-10, etc.).

The mintage of each individual medal - even within a series - is different; the numbers given in the table below are approximate averages for the series.

Each individual medal came in a plastic capsule, but no other packaging. Since the set became very popular, the Franklin Mint later offered a variety of packaging options, including individual frames, frames for a set of 5, and albums that would hold multiple frames.

Most of these medals are seen as loose medals, individually or in small groups, and some are seen as a Series, or multiple Series.

These are very rare.
