A 1965 quarter is almost certainly copper-nickel clad worth face value — weigh it: 5.67 g is clad, 6.25 g could be a rare silver-planchet error.

History

On July 23, 1965, President Lyndon B. Johnson signed the Coinage Act of 1965, eliminating silver from circulating dimes and quarters (the half dollar was debased from 90% to 40% silver). Rising silver prices had made the bullion in the coins worth nearly their face value, and widespread hoarding of silver coins caused a national coin shortage (Wikipedia).
The transition took three years: the last silver coins were dated 1964 while the new clad coins were dated 1965. The new quarters were lighter — 5.67 grams versus the silver standard of 6.25 grams — and carried no mint marks at all, because the Mint suspended mint marks on 1965–1967 coinage to discourage hoarding; with no mint mark it is impossible to tell which facility struck a given 1965 quarter (CoinWeek).
Because leftover 90% silver planchets were still on the production lines during the changeover, a small number of 1965 quarters were struck on silver planchets instead of clad ones — genuine transitional errors. Genuine examples are identified by a solid silver-gray edge with no copper band and a weight of 6.25 grams, versus the reddish-brown copper band visible on the edge of standard clad coins (bullionhunters.com; vocal.media). Reported auction prices for verified silver-planchet errors reach into the thousands of dollars, per auction records cited by uscoinsvalue.com.
Ordinary 1965 quarters are among the most common U.S. coins ever struck and are worth face value in circulated condition; only high uncirculated grades or verified errors carry premiums (bullionsharks.com; CoinWeek).

What is it worth

Reported auction prices for verified silver-planchet errors reach into the thousands of dollars, per auction records cited by uscoinsvalue.com.
1965 (no mint mark) — struck on 90% silver planchet transitional error (uscoinsvalue.com).
1965 — struck on silver dime planchet error (uscoinsvalue.com).
Ordinary 1965 quarters are worth face value in circulated condition; only high uncirculated grades or verified errors carry premiums (bullionsharks.com; CoinWeek).

What drives the premium

The premium belongs almost entirely to verified transitional errors: a small number of 1965 quarters were struck on leftover 90% silver planchets during the changeover instead of clad ones (bullionhunters.com; vocal.media).
High uncirculated grade is the other premium driver for ordinary pieces (CoinWeek).

How to identify the valuable variety

Check the edge first: a solid silver-gray edge with no visible copper band is the fastest screen for a possible silver planchet; standard clad coins show a reddish-brown copper stripe around the rim (bullionhunters.com).
Weigh on a scale accurate to 0.01 g: 5.67 g indicates clad; 6.25 g is consistent with a 90% silver quarter (CoinWeek; Heritage lists 6.25 g and 0.18085 oz ASW for silver Washington quarters).
The ring (ping) test and magnet test are folk methods: a faint magnetic attraction reflects the nickel content of clad coinage, and neither test confirms silver — only weight, edge, and professional authentication do (vocal.media).
Any claimed 1965 silver quarter should be authenticated by a major third-party grading service before being bought or sold as an error, since plated or altered coins are common (collector guidance).

Collector notes

Because the Mint suspended mint marks on 1965–1967 coinage to discourage hoarding, a 1965 quarter carries no mint mark and its striking facility cannot be identified (CoinWeek).
